: This input indicates to the
CL-PD67XX that the current card
access cycle is to be extended until
this signal becomes inactive (high).

Card Detect
: These inputs indicate to
the CL-PD67XX the presence of a
card in the socket. They are pulled
high internally in the chip.

-CE[2:1]
Card Enable
: These outputs are
driven low by the CL-PD67XX during
card access cycles to control
byte/word card access. -CE1 enables
even-numbered address bytes and
-CE2 enables odd-numbered address
bytes. When configured for 8-bit cards,
only -CE1 will be active and A0 will be
set to ‘1’ for odd-byte accesses.

RESET
Reset
: This output will be high to reset
the card and low for normal operation. To
reduce power consumption of idle cards
and to prevent reset glitches to a card,
this signal is high-impedance unless a
card is fully seated in the socket and
card interface signals are enabled.

: In Memory Card Interface mode,
this input serves as the BVD2 or bat-
tery warning status input.
In I/O Card Interface mode, this input
can be configured as a card’s -SPKR
binary audio input. For disk-drive sup-
port, BVD2/-SPKR/-LED can also be
configured as a drive-status LED input.
In DMA mode, this pin can be pro-
grammed as the -DREQ input from a
DMA-capable PC Card.

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
