|only 7.3 GB vs 7.4 GB First impressions. Good price, but I get only 7.3 GB when formatted with Canon SD 780 IS. As good as any. In the vast world of memory storage chips this is as good as any. Found this item on Amazon and the price was fair for a 4GB chip.|

NOTE: This signal is not supported on the PCI 1131. CardBus Device Select. When actively driven, this signal indicates that the PCI 1131 has decoded its address as the target of the current access. As an input, CDEVSEL indicates whether any device on the bus has been selected. CDEVSEL CSTSCHG I/O I CardBus Stop. This signal indicates the current target is requesting the initiator to stop the current transaction. CardBus Status Change. CSTSCHG is used to alert the system to a change in the READY, WP, or BVD condition of the l/O CardBus PC Card. CardBus Audio. This signal is an optional digital input signal from a PC Card to the system's speaker. CardBus cards support two types of audio: single amplitude, binary waveform, and/or Pulse Width Modulation (PWM) encoded signal. The PCI1131 supports the Binary Audio Mode, and may output a binary audio signal from the PC Card to the SPKROUT signal. CIRDY I/O CardBus Initiator Ready. This signal indicates that the PCI1131 is initiating the bus initiator ability to complete a current data phase of the transaction. It is used in conjunction with CTRDY. When both of these signals are sampled asserted, a data phase is completed on any clock. During a write, CIRDY indicates that valid data is present on CAD31-0, and during a read, it indicates the PCI 1131, as an initiator, is prepared to accept the data. Wait cycles are inserted until both CTRDY and CFRDY are both low (asserted). CardBusTargetReady. This signal indicates that the PCI 1131, as a selected targets has the ability to complete a current data phase of the transaction. It is used in conjunction with CIRDY. When both of these signals are sampled asserted, a data phase is completed on any clock. During a read, CTRDY indicates that valid data is present on CAD31-0, and during a write, it indicates the PCI 1131, as a target, is prepared to accept the data. Wait cycles are inserted until both CIRDY and CTRDY are both low (asserted). CardBus Cycle Frame. This signal is driven by the PCI 1131 when it is acting as an initiator to indicate the beginning and duration of a transaction. CFRAME is asserted to indicated a bus transaction is beginning, and while it is asserted, data transfer is continuous. When CFRAME is high (deasserted), the transaction is in its final data phase.

CardBus PC Card Interface Control Signals (Slots A and B) I O CardBus Request. This signal ir1dicates to the arbiter that the CardBus PC Card desires use the CardBus bus. CardBus Grant. This signal is driven by the PCI 1131 to grant a CardBus PC Card access to the CardBus bus after the current data transaction has completed CardBus Parity Error. This signal reports errors during all CardBus PC Card transactions except during special cycles. This signal is sustained in a high-impedance state and must be driven active by the agent receiving data, two clocks following the data, when a data parity error is detected. This signal must be driven active for a minimum duration is one clock for each data phase. CPERR must be driven high for one clock before it is returned to the high-impedance state. An agent cannot report a CPERR until it has claimed the access by asserting CDSVSEL and completed a data phase. CardBus System Error. This signal reports address parity error, data errors on the Special Cycle command, or any other system error where the result could be catastrophic, such that the CardBus card may no longer operate correctly. CSERR is open drain and is actively driven for a single CardBus PC Card clock by the agent reporting the error. The assertion of this signal is synchronous to the Cock and meets the setup and hold times of all bussed signals. Restoring of the CSERR to the deasserted states is accomplished by a weak pull-up which is provided by the system designer. This pull-up may take two to three clock periods to fully restore ~R The PCI1131 reports CSERR to the operating system anytime it is sampled low (asserted) CardBus Voltage Sense 1 and Voltage Sense 2. CVS1 and CVS2, are used in conjunction with each other, along with CCD1 and CCD2, to determine the operating voltage of the CardBus PC Card. CardBus Interrupt.

UARTs Ring Indicator. When low, this indicates that a telephone ring signal has been received by the modem. The /RI signal is a modem status input whose condition is tested by the CPU by reading bit 6 (RI) of the Modem Status Register (MSR) for the appropriate serial channel. Bit 6 is the complement of the RI signal. Bit 2 ( TERI) of the MSR indicates whether the RI input has changed from low to high since the previous reading of the MSR. NOTE: When the TERI bit of the MSR is set and Modem Status interrupts are enabled, an interrupt is generated.
UARTs Request to Send. When low, this output indicates to the modem or data set that the UART is ready to exchange data. The RTS signal can be set to an active low by programming bit 1 (RTS) of the Modem Control Register to a high level. A Master Reset operation sets this signal to its inactive (high) state. Loop mode operation holds this signal to its inactive state. UARTs Serial Input. This input receives composite serial data from the communications link (peripheral device, modem, or data set). System interrupt 1, 2, and 3. This input can be routed to one of the following output pins: IRQ3-IRQ7, IRQ9-IRQ12. SIRQ12 and SIRQ13 can be also routed to IRQ15. Software configuration determines to which output pin the input pin is routed to. SIRQ1 is multiplexed with IRQ15, SRIQ12 is multiplexed with DRATE1/MSEN1/CS0, and SIRQ3 is multiplexed with DRV2/PNF/DR23.

When this signal is low, it selects the printer. This pin is in a tristate condition 10 ns after a 0 is loaded into the corresponding Control Register bit. The system should pull this pin high using a 4.7 K resistor. UARTs Serial Output. This output sends composite serial data to the communications link (peripheral device, modem, or data set). The SOUT signal is set to a marking state (logic 1) after a Master Reset operation. Parallel Port Data Strobe. This output indicates to the printer that a valid data is available at the printer port. This pin is in a tristate condition 10 ns after a 0 is loaded into the corresponding Control Register bit. The system should pull high using a 4.7 K. FDC Step. This output signal issues pulses to the disk drive at a software programmable rate to move the head during a seek operation. FDC Step.
