CL-PD6730 Pin Descriptions (continued)
Pin
Name
Socket Interface Pins (continued)
-INPACK
Input Acknowledge: The -INPACK
function is not applicable in PCI bus
environments. However, for
compatibility with other Cirrus Logic
products, this pin should be
connected to the PC Card socket's -
INPACK pin.
RDY/
Ready / Interrupt Request: In
-IREQ
Memory Card Interface mode, this
input indicates to the CL-PD6730
that the card is either ready or busy.
In l/O Card Interface mode, this input
indicates a card interrupt request.
-WAIT
Wait: This input indicates a request
by the card to the CL-PD6730 to
delay the cycle in progress until this
signal is deasserted.
-CD[2:1]
Card Detect: These inputs indicate
to the CL-PD6730 that a card is in
the socket. They are internally pulled
high to the voltage of the +5V power
pin.
-CE[2:1]
Card Enable: These outputs are
driven low by the CL-PD6730 during
card access cycles to control
byte/word card access. -CE1 enables
even-numbered address bytes, and -
CE2 enables odd-2 or 3 numbered
address bytes. When configured for
8-bit cards, only -CE1 is active and
A0 is used to indicate access of odd-
or even-numbered bytes.
RESET
Card Reset: This output is low for
normal operation and goes high to
reset the card. To prevent reset
glitches to a card, this signal is high-
impedance unless a card is seated in
the socket, card power is applied,
and the card's interface signals are
enabled.
