PRELIMINARY DATA SHEET v3.1
PIN INFORMATION
-WE
Write Enable
: For non-DMA transfers,
this signal goes active (low) to indicate
a memory write to the socket.
During a DMA read (when -IOWR is
active), this signal goes low if the ISA
output TC is active (high), indicating to
the card that the system’s terminal
count signal is active. During DMA
writes (when -IORD is active), this out-
put remains high.

Write Protect / I/O Is 16-Bit
: In Mem-
ory Card Interface mode (Interrupt and
General Control register, bit 5 is equal
to ‘0’), this input is the status of the PC
card write protect switch.
In I/O Card Interface mode, a low on
this input indicates that the I/O
address being accessed is capable of
16-bit operation.
In DMA mode, this pin can be pro-
grammed as the -DREQ input from a
DMA-capable PC Card.

Input Acknowledge
: This input indi-
cates to the CL-PD67XX that the PC
Card supports I/O access at the cur-
rent address. A PC Card activates this
input during IORD cycles to which the
card can respond.
In DMA mode, this pin can be pro-
grammed as the -DREQ input from a
DMA-capable PC Card.

Ready / Interrupt Request
: In Mem-
ory Card Interface mode, this input is
readable as the status of bit 5 of the
Interface Status
register, which is
used by a PC Card to signal system
software of its ready or busy state.
In I/O Card Interface mode, this active-
low input indicates an interrupt
request.

To differentiate the sockets, all CL-PD6722 pin names have either A_ or B_ prepended to the pin names indicated. For
example, A_A[25:0] and B_A[25:0] are the independent address buses to the sockets.

When a socket is configured as an ATA drive interface, socket interface pin functions change. See
Table 11-1 on page 75
