The frequency of this repetition per second is called Vertical Frequency or Refresh Rate. Unit: Hz
Example: If the same light repeats itself 60 times per second, this is regarded as 60 Hz.
Horizontal Frequency The time to scan one line connecting the right edge to the left edge of the screen horizontally is called Horizontal Cycle. The inverse number of the Horizontal Cycle is called Horizontal Frequency. Unit: kHz Interlace and Non-Interlace Methods Showing the horizontal lines of the screen from the top to the bottom in order is called the NonInterlace method while showing odd lines and then even lines in turn is called the Interlace method. The Non-Interlace method is used for the majority of monitors to ensure a clear image. The Interlace method is the same as that used in TVs. Plug & Play This is a function that provides the best quality screen for the user by allowing the computer and the monitor to exchange information automatically. This monitor follows the international standard VESA DDC for the Plug & Play function. Resolution The number of horizontal and vertical dots used to compose the screen image is called 'resolution'. This number shows the accuracy of the display. High resolution is good for performing multiple tasks as more image information can be shown on the screen. Example: If the resolution is 1280 x 1024 , this means the screen is composed of 1280 horizontal dots (horizontal resolution) and 1024 vertical lines (vertical resolution).

For Better Display

1. Adjust computer resolution and screen injection rate (refresh rate) oncomputer as described below to enjoy the best quality of picture. You can have an uneven quality of picture in the screen if the best quality of picture is not provided in TFT-LCD.
Resolution: 1280 x 1024 Vertical frequency (refresh rate): 60 Hz 2. TFT LCD panel manufactured by using advanced semiconductor technology with precision of 99.999% above is used for this product. But the pixels of RED, GREEN, BLUE and WHITE color seem to be bright sometimes or some of black pixels could be seen. This is not from bad quality and you can use it without uneasiness. For example, the number of TFT LCD pixels that is contained in this product are 3,932,160. 3. When you clean the monitor and the panel outside, please apply the recommended small amount of cleaner by using soft and dry cloth and polish it. Let LCD area not to be forced but to be scrubbed out softly. If excessive force is applied, you can have a stain on it. 4. If you are not satisfied with the quality of picture, you can get better quality of picture by executing "auto adjustment function" in display screen that is appeared as window termination button is pressed. If there's still noise after automatic adjustment, use FINE/COARSE adjustment function. 5. If you view a fixed screen for an extended period of time, residual image or blurriness may appear. Change the mode to energy save or set a screensaver to moving picture when you need to be away from the monitor for an extended period of time.

&1$'&1%23'4 Executing the Enable Interrupts (EI) instruction globally enables the interrupt structure. All interrupts are then serviced as they occur according to the established priorities. % The system initialization routine executed after a reset must always contain an EI instruction to globally enable the interrupt structure. During the normal operation, you can execute the DI (Disable Interrupt) instruction at any time to globally disable interrupt processing. The EI and DI instructions change the value of bit 0 in the SYM register. (%%5 In addition to the control registers for specific interrupt sources, four system-level registers control interrupt processing: The interrupt mask register, IMR, enables (un-masks) or disables (masks) interrupt levels. The interrupt priority register, IPR, controls the relative priorities of interrupt levels. The interrupt request register, IRQ, contains interrupt pending flags for each interrupt level (as opposed to each interrupt source). The system mode register, SYM, enables or disables global interrupt processing (SYM settings also enable fast interrupts and control the activity of external interface, if implemented).
Interrupt mask register Interrupt priority register ' IMR IPR $0 R/W R/W
Bit settings in the IMR register enable or disable interrupt processing for each of the eight interrupt levels: IRQ0IRQ7. Controls the relative processing priorities of the interrupt levels. The seven levels of S3C8238/C8235/F8235 are organized into three groups: A, B, and C. Group A is IRQ0 and IRQ1, group B is IRQ2, IRQ3 and IRQ4, and group C is IRQ5, IRQ6, and IRQ7. This register contains a request pending bit for each interrupt level. This register enables/disables fast interrupt processing, dynamic global interrupt processing, and external interface control (An external memory interface is implemented in the S3C8238/C8235/F8235 microcontroller).

$!"# $. If you use an external interrupt for Stop mode release, you can also program the duration of the oscillation stabilization interval. To do this, you must make the appropriate control and clock settings before entering Stop mode. When the Stop mode is released by external interrupt, the CLKCON.4 and CLKCON.3 bit-pair setting remains unchanged and the currently selected clock value is used. The external interrupt is serviced when the Stop mode release occurs. Following the IRET from the service routine, the instruction immediately following the one that initiated Stop mode is executed. #"-!-"- $-- $$%6 )# )6)* Activate any enabled interrupt, causing stop mode to be released.

(Keep the order)
Idle mode is invoked by the instruction IDLE (opcode 6FH). In idle mode, CPU operations are halted while some peripherals remain active. During idle mode, the internal clock signal is gated away from the CPU, but all peripherals timers remain active. Port pins retain the mode (input or output) they had at the time idle mode was entered. There are two ways to release idle mode: 1. Execute a reset. All system and peripheral control registers are reset to their default values and the contents of all data registers are retained. The reset automatically selects the slow clock fxx/16 because CLKCON.4 and CLKCON.3 are cleared to 00B. If interrupts are masked, a reset is the only way to release idle mode. 2. Activate any enabled interrupt, causing idle mode to be released. When you use an interrupt to release idle mode, the CLKCON.4 and CLKCON.3 register values remain unchanged, and the currently selected clock value is used. The interrupt is then serviced. When the return-from-interrupt (IRET) occurs, the instruction immediately following the one that initiated idle mode is executed.
The S3C8238/C8235/F8235 microcontroller has five bit-programmable I/O ports, P0-P4. The port 3 and port 4 are 4-bit ports and the others are 8-bit ports. This gives a total of 32 I/O pins. Each port can be flexibly configured to meet application design requirements. The CPU accesses ports by directly writing or reading port registers. No special I/O instructions are required. Table 9-1 gives you a general overview of the S3C8238/C8235/F8235 I/O port functions.

The port 0 interrupt pending register P0PND lets you check for interrupt pending conditions and clear the pending condition when the interrupt service routine has been initiated. The application program detects interrupt requests by polling the P0PND register at regular intervals. When the interrupt enable bit of any port 0 pin is 1, a rising or falling signal edge at that pin will generate an interrupt request. The corresponding P0PND bit is then automatically set to 1 and the IRQ level goes low to signal the CPU that an interrupt request is waiting. When the CPU acknowledges the interrupt request, application software must the clear the pending condition by writing a 0 to the corresponding P0PND bit.

You can use the basic timer (BT) in two different ways: As a watchdog timer to provide an automatic reset mechanism in the event of a system malfunction. To signal the end of the required oscillation stabilization interval after a reset or a Stop mode release. The functional components of the basic timer block are: Clock frequency divider (fxx divided by 4096, 1024 or 128) with multiplexer 8-bit basic timer counter, BTCNT (set 1, bank 0, FDH, read-only) Basic timer control register, BTCON (set 1, D3H, read/write)
The basic timer control register, BTCON, is used to select the input clock frequency, to clear the basic timer counter and frequency dividers, and to enable or disable the watchdog timer function. It is located in set 1, address D3H, and is read/write addressable using register addressing mode. A reset clears BTCON to '00H'. This enables the watchdog function and selects a basic timer clock frequency of f/4096. To disable the watchdog function, write the signature code '1010B' to the basic timer register control bits BTCON.7BTCON.4. The 8-bit basic timer counter, BTCNT (set 1, bank 0, FDH), can be cleared at any time during normal operation by writing a "1" to BTCON.1. To clear the frequency dividers, write a "1" to BTCON.0.

% &!'( ! You can program the basic timer overflow signal (BTOVF) to generate a reset by setting BTCON.7BTCON.4 to any value other than "1010B". (The "1010B" value disables the watchdog function.) A reset clears BTCON to "00H", automatically enabling the watchdog timer function. A reset also selects the CPU clock (as determined by the current CLKCON register setting), divided by 4096, as the BT clock. The MCU is reseted whenever a basic timer counter overflow occurs, During normal operation, the application program must prevent the overflow, and the accompanying reset operation, from occuring, To do this, the BTCNT value must be cleared (by writing a 1 to BTCON.1) at regular intervals. If a system malfunction occurs due to circuit noise or some other error condition, the BT counter clear operation will not be executed and a basic timer overflow will occur, initiating a reset. In other words, during the normal operation, the basic timer overflow loop (a bit 7 overflow of the 8-bit basic timer counter, BTCNT) is always broken by a BTCNT clear instruction. If a malfunction does occur, a reset is triggered automatically. ""! !)"*! !+" ! You can also use the basic timer to program a specific oscillation stabilization interval following a reset or when Stop mode has been released by an external interrupt. In Stop mode, whenever a reset or an external interrupt occurs, the oscillator starts. The BTCNT value then starts increasing at the rate of fxx/4096 (for reset), or at the rate of the preset clock source (for an external interrupt). When BTCNT.4 overflows, a signal is generated to indicate that the stabilization interval has elapsed and to gate the clock signal off to the CPU so that it can resume normal operation. In summary, the following events occur when stop mode is released: 1. During stop mode, a power-on reset or an interrupt occurs to trigger the Stop mode release and oscillation starts. 2. If a power-on reset occurred, the basic timer counter will increase at the rate of fxx/4096. If an interrupt is used to release stop mode, the BTCNT value increases at the rate of the preset clock source. 3. Clock oscillation stabilization interval begins and continues until bit 4 of the basic timer counter overflows. 4. When a BTCNT.4 overflow occurs, normal CPU operation resumes.

The 8-bit timer A is an 8-bit general-purpose timer/counter. Timer A has three operating modes, you can select one of them using the appropriate TACON setting: Interval timer mode (Toggle output at TAOUT pin) Capture input mode with a rising or falling edge trigger at the TACAP pin PWM mode (TAPWM) Timer A has the following functional components: Clock frequency divider (fxx divided by 1024, 256, or 64 ) with multiplexer External clock input pin ( TACK) 8-bit counter (TACNT), 8-bit comparator, and 8-bit reference data register (TADATA) I/O pins for capture input (TACAP) or PWM or match output (TAPWM, TAOUT) Timer A overflow interrupt (IRQ0, vector E0H) and match/capture interrupt (IRQ0, vector DEH) generation Timer A control register, TACON (set 1, bank0, EAH, read/write)
!" # The timer A module can generate two interrupts: the timer A overflow interrupt (TAOVF), and the timer A match/ capture interrupt (TAINT). TAOVF is interrupt level IRQ0, vector E0H. TAINT also belongs to interrupt level IRQ0, but is assigned the separate vector address, DEH. A timer A overflow interrupt pending condition is automatically cleared by hardware when it has been serviced. A timer A match/capture interrupt, TAINT pending condition is also cleared by hardware when it has been serviced. $!% The timer A module can generate an interrupt: the timer A match interrupt (TAINT). TAINT belongs to interrupt level IRQ0, and is assigned the separate vector address, DEH. When timer A measure interrupt occurs and is serviced by the CPU, the pending condition is cleared automatically by hardware. In interval timer mode, a match signal is generated and TAOUT is toggled when the counter value is identical to the value written to the TA reference data register, TADATA. The match signal generates a timer A match interrupt (TAINT, vector DEH) and clears the counter. If, for example, you write the value 10H to TADATA and 0AH to TACON, the counter will increment until it reaches 10H. At this point, the TA interrupt request is generated, the counter value is reset, and counting resumes. %"&'"%!'" Pulse width modulation (PWM) mode lets you program the width (duration) of the pulse that is output at the TAPWM pin. As in interval timer mode, a match signal is generated when the counter value is identical to the value written to the timer A data register. In PWM mode, however, the match signal does not clear the counter. Instead, it runs continuously, overflowing at FFH, and then continues incrementing from 00H. Although you can use the match signal to generate a timer A overflow interrupt, interrupts are not typically used in PWM-type applications. Instead, the pulse at the TAPWM pin is held to Low level as long as the reference data value is less than or equal to ( ) the counter value and then the pulse is held to High level for as long as the data value is greater than ( > ) the counter value. One pulse width is equal to t 256. !'" In capture mode, a signal edge that is detected at the TACAP pin opens a gate and loads the current counter value into the TA data register. You can select rising or falling edges to trigger this operation. Timer A also gives you capture input source: the signal edge at the TACAP pin. You select the capture input by setting the value of the timer A capture input selection bit in the port 3 control register, P3CON, (set 1, bank 1, E8H). When P3CONL.7.6 is 00, the TACAP input or normal input is selected. When P3CON.7.6 is set to 10, normal output is selected. Both kinds of timer A interrupts can be used in capture mode: the timer A overflow interrupt is generated whenever a counter overflow occurs; the timer A match/capture interrupt is generated whenever the counter value is loaded into the TA data register. By reading the captured data value in TADATA, and assuming a specific value for the timer A clock frequency, you can calculate the pulse width (duration) of the signal that is being input at the TACAP pin.

15$-$6$ The LCD segment output pins(SEG12-SEG23) can also output key strobe signal for key scan and KIN0-KIN3 pins check key-press. When SEG12-SEG23 are set as key strobe output, selected key strobe is output pin by pin continuously with selected interval and duration. When KIN# pins are set as an alternative mode, KIN# pins status is high impedance normally, but when key strobe is output through SEG# pins, KIN# pins status become pull-up enable input mode. To decide which SEG# pin output key strobe you should check P2 and P4 data register. If all SEG12-SEG23 are used as key strobe output, KSDATA data register are used as one 12-bit data register. If SEG16-SEG23 are used as key strobe output, KSDATA data register constains one number between 5 and 12. If SEG20-SEG23 are used as key strobe output, KSDATA data register constains one number between 9 and 12. KSDATA data register value is not changed until next strobe occurs. To decide which KIN# pin receive key strobe you should check P3PND register in interrupt routine. So, check KSDATA data register and P3PND register and you will get the key-press information.

Samsung provides a powerful and easy-to-use development support system in turnkey form. The development support system is configured with a host system, debugging tools, and support software. For the host system, any standard computer that operates with MS-DOS as its operating system can be used. One type of debugging tool including hardware and software is provided: the sophisticated and powerful in-circuit emulator, SMDS2+, for S3C7, S3C9, S3C8 families of microcontrollers. The SMDS2+ is a new and improved version of SMDS2. Samsung also offers support software that includes debugger, assembler, and a program for setting options.
Samsung Host Interface for In-Circuit Emulator, SHINE, is a multi-window based debugger for SMDS2+. SHINE provides pull-down and pop-up menus, mouse support, function/hot keys, and context-sensitive hyper-linked help. It has an advanced, multiple-windowed user interface that emphasizes ease of use. Each window can be sized, moved, scrolled, highlighted, added, or removed completely.
The Samsung Arrangeable Microcontroller (SAM) Assembler, SAMA, is a universal assembler, and generates object code in standard hexadecimal format. Assembled program code includes the object code that is used for ROM data and required SMDS program control data. To assemble programs, SAMA requires a source file and an auxiliary definition (DEF) file with device specific information. The SASM88 is a relocatable assembler for Samsung's S3C8-series microcontrollers. The SASM88 takes a source file containing assembly language statements and translates into a corresponding source code, object code and comments. The SASM88 supports macros and conditional assembly. It runs on the MS-DOS operating system. It produces the relocatable object code only, so the user should link object file. Object files can be linked with other object files and loaded into memory. HEX2ROM file generates ROM code from HEX file which has been produced by assembler. ROM code must be needed to fabricate a microcontroller which has a mask ROM. When generating the ROM code (.OBJ file) by HEX2ROM, the value "FF" is filled into the unused ROM area up to the maximum ROM size of the target device automatically. Target boards are available for all S3C8-series microcontrollers. All required target system cables and adapters are included with the device-specific target board.
