PD6722
Qty. I/O Pwr. Drive
Socket A Socket B
Register Access: In Memory Card
Interface mode, this output chooses
between attribute and common
memory. In I/O Card Interface mode for
non-DMA transfers, this signal is active
(low).
-REG
For DMA cycles on the PD6722 to a
8
DMA-capable card, -REG is inactive
during I/O cycles to indicate a DMA
cycle to or from the PC Card.
In ATA mode, this signal is always
inactive.

I/O 2 or 3 2 mA
Output Enable: For non-DMA
transfers, this output goes active (low)
to indicate a memory read from the
socket.
During a DMA write (when -IORD is
-OE
active) this output goes low if the ISA
26
output TC is active (high), indicating to
the card that the system’s terminal
count signal is active. During DMA
reads (when -IOWR is active), this
output remains high.

1. 1To differentiate the sockets, all 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.
2. 2When a socket is configured as an ATA drive interface, socket interface pin functions change. See Table 17 on page 88.
