I/O Power
-CD[2:1]/
CCD[2:1]#
Card Detect: These inputs indicate to the
CL-PD6832 that a card is in the socket.
They are internally pulled high to the
voltage of the +5V power pin. In CardBus
mode, these inputs are used in conjunction
with CVS[2:1] to detect the presence and
type of card.

-CE2/
CAD10
Card Enable pin is driven low by the CL-
PD6832 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
is active and A0 is used to indicate access
of odd- or even-numbered bytes. In
CardBus mode, this pin is the CardBus
address/data bit 10

CC/BE0#
Card Enable pin is driven low by the CL-
PD6832 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
is active and A0 is used to indicate access
of odd- or even-numbered bytes. In
CardBus mode, this pin is the CardBus
C/BE0# signal.

RESET/
CRST#
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.
In CardBus mode, this pin is the RST# input
to the card, which is active-low.

-LED/CAUDIO
Battery Voltage Detect 2 / Speaker / LED:
In Memory Card Interface mode, this input
serves as the BVD2 (battery warning status)
input. In l/O Card Interface mode, this input
can be configured as a card's -SPKR binary
audio input. For ATA or non-ATA (SFF-68)
disk-drive support, this input can also be
configured as a drive-status LED input. In
CardBus mode, this pin is the AUDIO input
from the card.
