(All Modes: UDMA Read
protocol active)

This signal is not used by the CF Card, and is pulled up to
VCC through a 4.7K ohm resistor.
In all modes, when Ultra DMA mode DMA Write is active, this
signal is asserted by the device during a data burst to
indicate that the device is ready to receive Ultra DMA data
out bursts. The device may negate -DDMARDY to pause an
Ultra DMA transfer.
In all modes, when Ultra DMA mode DMA Read is active, this
signal is the data in 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 in burst
-WAIT
(PC Card I/O Mode except
UDMA protocol active)
-DDMARDY
(All Modes: UDMA Write
protocol active)
DSTROBE
(All Modes: UDMA Read
protocol active)
This signal is not used by the CF Card, and is pulled up to
VCC through a 4.7K ohm resistor.
Same as -DDMARDY above.
Same as DSTROBE above.
IORDY
(TrueIDE Mode except
UDMA protocol active)
-DDMARDY
(All Modes: UDMA Write
protocol active)
DSTROBE
(All Modes: UDMA Read
protocol active)
This signal is not used by the CF Card, and is pulled up to
VCC through a 4.7K ohm resistor.
Same as -DDMARDY above.
Same as DSTROBE above.

RESET
(PC Card Memory Mode)
I
41
When RESET is high, this signal resets the CF Card. The CF
Card is reset only at power up if this signal is left high or
open from power-up. The CF Card can also be reset when
the soft reset bit in the Configuration Option Register is set.
RESET
(PC Card I/O Mode)
This signal is the same as the PC Card Memory Mode signal.
-RESET
(TrueIDE Mode)
In the TrueIDE Mode this input pin is the active low hardware
reset from the host.
