Resets the card (active High). The card is reset at power-up
only if this pin is left High or unconnected.
Same as PC card memory mode.
Hardware reset from the host (active Low).
+5 V, +3.3 V power.
Same for all modes.
Same for all modes.
Voltage sense signals.–VS1 is grounded so that the CIS
can be read at 3.3 volts and –VS2 is reserved by PCMCIA
for a secondary voltage.
Same for all modes.
Same for all modes.
Numonyx CF does not assert the WAIT (IORDY) signal
In True IDE mode, except in Ultra DMA mode, this output
signal may be used as IORDY.
In True IDE mode, when Ultra DMA mode DMA Write is
active, this signal is asserted by the host to indicate that the
device is read to receive Ultra DMA data-in bursts.
The device may negate -DDMARDY to pause an Ultra DMA
transfer.
In True IDE mode, when Ultra DMA mode DMA Write is
active, this signal is the data out strobe generated by the
device. Both the rising and falling edge of DSTROBE cause
data to be latched by the host. The device may stop
generating DSTROBE edges to pause an Ultra DMA data-
out burst.
