Description
This signal is not used in this mode.
The Input Acknowledge signal is asserted by the CompactFlash
Storage Card when the card is selected and responding to an I/O
O
43
read cycle at the address that is on the address bus. This signal is
used by the host to control the enable of any input data buffers
between the CompactFlash Storage Card and the CPU.
In True IDE Mode this output signal is not used and should not be
connected at the host.
This signal is not used in this mode.
This is an I/O Read strobe generated by the host. This signal gates
I
34
I/O data onto the bus from the CompcatFlash Storage Card when
the card is configured to use the I/O interface.
In True IDE Mode, this signal has same function as in PC Card I/O
Mode.
This signal is not used in this mode.
The I/O Write strobe pulse is used to clock I/O data on the Card
Data bus into the CompactFlash Storage Card controller registers
when the CompactFlash Storage Card is configured to use the I/O
I
35
interface.
The clocking will occur on the negative to positive edge of the
signal (trailing edge)
In True IDE Mode, this signal has the same function as in PC Card
I/O Mode.
This is an Output Enable strobe generated by the host interface .It
is used to read data from the CompactFlash Storage Card in
Memory Mode and to read the CIS and configuration registers.
I

In PC Card I/O Mode, this signal is used to read the CIS and
configuration registers.
To enable True IDE Mode this input should be grounded by the
host.
