5. PCB PARTS LIST

Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 561... RD1/4PU 1 J 560 473... RD1/4PU 3 J 47k 0.5 R50... RN2H R K 1 1R0... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5621.. RN1/4PC F 5.62k

These are 8 bit I/O ports with the same functions as P0. By software selection, it functions as the input terminals for the timers B0 to B2, the output terminals for the D/A converter, the expansion input terminals of the A/D converter, or the A/D trigger input terminals. This is the terminal for switching the external data bus width. When the level of this terminal is "L", the width is 16 bits, and when it is "H", the width is 8 bits. Please fix it to one of these levels. At the time of single-chip mode, connect it to the Vss terminal. This is the terminal for processor mode switching. At the time of single-chip mode or at the time of memory expansion mode, connect it to the Vss terminal. At the time of microprocessor mode, connect it to the Vcc terminal. P80 to P84, P86, and P87 are I/O ports with the same functions as P0. By software selection, they function as the I/O terminals for the timer A4 or the input terminals for external interrupt. P86 and P87 function by software selection as the I/O terminals for the subclock oscillation circuit. In this case, connect a crystal oscillator between P86 (XCOUT terminal) and P87 (XCIN terminal). P85 is an input-only port serving also as NMI. When the input of this terminal changes from "H" to "L", and NMI interrupt is generated. The NMI function can not be cancelled by software. A pullup resistance can not be set for this terminal. When the input to this terminal is "L", the microcomputer is reset. This are the I/O terminals of the main clock oscillation circuit. Connect a ceramic oscillator or a crystal oscillator between the terminals XIN and XOUT. In case of an externally generated clock, enter the clock from the XIN terminal and leave the XOUT terminal open. Impress 0 V. Impress 2.7 V to 5.5 V. These are 8 bit I/O ports with the same functions as P0. By software selection, they function as the I/O terminals for the timers A0 to A3. These are 8 bit I/O ports with the same functions as P0. By software selection, they function as the I/O terminals for the UART0 and UART1. These are 8 bit I/O ports with the same functions as P0. By software selection, they put out a clock with 1/8 or 1/32 of XIN or with the same cycle as XCIN from P57. WRL, WRH, (WR, BHE), RD, BCLK, HLDA, and ALE signals are put out. Switching between WRL and WRH and between BHE and WR is possible by software. At the time of WRL, WRH, RD selection When the external data bus width is 16 bits and the WRL signal is at "L" level, writing is done to an even address, and the WRH signal is at "L" level, writing is done to an odd address. Reading is performed when the RD signal is at "L" level. At the time of WR, BHE, RD selection Writing is done when the WR signal is at "L" level. Reading is done when the RD signal is at "L" level. An odd address is accessed when the BHE signal is at "L" level. Please use this mode when the external data bus width is 8 bits. The microcomputer is in hold status while the input level to the HOLD terminal is "L". During hold status, the output from HLDA is at "L" level. ALE is the signal for address latching. The microcomputer is in ready status while the input to RDY is at "L" level. A clock with the same frequency as the internal clock is put out from the BCLK terminal. These are 8 bit I/O ports with the same functions as P0. The A16 to A19 and CS0 to CS3 signals are put out. A16 to A19 are the upper 4 bits of the address. CS0 to CS3 are the chip select signals, and they are used for specification of the access space.

These are 8 bit I/O ports with the same functions as P0. The middle 8 bits (A8 to A15) of the address are put out. With an external data bus width of 16 bits and multiplex bus setting, time sharing is performed for data (D7) I/O and address (A8) output. Address (A9 to A15) output also is performed. Impress 2.7 V to 5.5 V. Impress 0 V. These are 8 bit I/O ports with the same functions as P0. Output of the lower 8 bits (A0 to A7) of the address is performed. With an external data bus width of 16 bits and multiplex bus setting, time sharing is performed for data (D0 to D7) I/O and address lower 8 bits (A0 to A7) output. With an external data bus width of 16 bits and multiplex bus setting, time sharing is performed for data (D0 to D6) I/O and address (A1 to A7) output. Address (A0) output also is performed. These are 8 bit I/O ports with the same functions as P0. Data (D8 to D15) I/O is performed at the time of separate bus setting. These are CMOS 8 bit I/O ports. They have direction registers for I/O selection, and input or output port setting is possible individually for each terminal. For an input port, the existence or absence of a pull-up resistance can be set by software in 4 bit units. Data (D0 to D7) I/O is performed at the time of separate bus setting. This are 8 bit I/O ports with the same functions as P0. By software selection, they function as input terminals of the A/D converter. P104 to P107 also function as input terminals for the key input interrupt function. This is the A/D converter power supply input terminal. Please connect it to the Vss terminal. This is the A/D converter reference voltage input terminal. This is the A/D converter power supply input terminal. Please connect it to the Vcc terminal.

Notes) PCMD is an MSB first. two's complement output. GTOP is used to monitor the frame sync protection status. (High:sync protection window released) XUGF is the negative pulse for the frame sync derived from the EFM signal. It is the signal before sync protection. XPLCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge of XPLCK and the EFM signal transition point coincide. GFS goes high when the frame sync and the insertion protection timing match. RFCK is derived with the crystal accuracy. This signal has a cycle of 136s. C2PO represents the data error status. XRAOF is generated when the 16K RAM exceeds the 4F jitter margin.

Additional Laser Caution

1. Laser Interlock Mechanism The loading position detect switch (in CD mechanism assembly) is set to "CLMP ON(CD CLOSE)" (ON:low level,OFF:high level) position, the system control IC(IC5501) get the "CLMP" signal, and hand the laser "LDON" signal to IC1101. Then a laser diode can be lighted except when the level of signal CLMP is low. The interlock also does not function in the test mode*. Laser diode oscillation will continue, if pin 1 of CXA1821M (IC1101) on the CDMAIN UNIT is connected to GND, or pin 19 is connected to low level (ON), or else the terminals of Q1101 are shorted to each other (fault condition).
