HB286008C2, HB286015C2, HB286030C2
Battery voltage detection, Digital audio output, Disk active/slave present (BVD2, -SPKR, -DASP:
output/output): In memory card mode, BVD2 outputs the battery voltage status in the card. This card has
no battery, so this output is high level constantly. In I/O card mode, -SPKR is held High because this card
dose not have digital audio output. In True IDE Mode -DASP is the Disk Active/Slave Present signal in the
Master/Slave handshake protocol.
Reset (RESET, -RESET: input): By assertion of RESET signal, all registers of this card are cleared and
RDY/-BSY signal turns to high level. In True IDE Mode -RESET is the active low hardware reset from the
host.
Wait (-WAIT, IORDY: output): This signal outputs low level for the purpose of delaying memory access
cycle or I/O access cycle. In True IDE Mode this output signal may be used as IORDY.
Input acknowledge (-INPACK: output): This signal not used for memory card mode. This signal is
asserted by this card when the card is selected and responding to an I/O read cycle at the address that is on the
address bus. This signal is used for the input data buffer control. In True IDE Mode this output signal is not
used and should not be connected at the host.
Battery voltage detection, Status change Pass diagnostic (BVD1, -STSCHG, -PDIAG: input/output): In
memory card mode, BVD1 outputs the battery voltage status in the card. This card has no battery, so this
output is high level constantly. In I/O card mode, -STSCHG is used for changing the status of Configuration
status register in Attribute area, while the card is set I/O card interface. In True IDE Mode, -PDIAG is the
Pass Diagnostic signal in Master/Slave handshake protocol.
VCC voltage sense (-VS1, -VS2: output): This signals are intended to notify the socket of PC Card's CIS
VCC requirement. VS1 is held low and VS2 is nonconnected in this card.
Card select (-CSEL: input): This signal is not used for memory card mode and I/O card mode. This
internally pulled up signal is used for configure this device as a Master or a Slave when configured in the
True IDE Mode. When this pin is grounded, this device is configured as a Master. When the pin is open, this
device is configured as a Slave.
