LED: In Memory Card Interface mode,
this input serves as the BVD2 (battery
warning status) input. In I/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.
CardBus Audio: In CardBus mode,
this pin is the CAUDIO input.

Card Interface mode, this input serves
-CSTSCHG
as the BVD1 (battery-dead status)
input. In I/O Card Interface mode, this
input is the -STSCHG input, which
indicates to the OZ6833 that the card’s
internal status has changed. If bit 7 of
the Interrupt and General Control
register is set to `1`, this pin serves as
the ring indicate input for wakeup-on-
ring system power management
support.
CardBus Status Change: In CardBus
mode, this pin is the CSTSCHG. This
pin can be used to generate PME#.

conjunction with VS1 to determine the
operating voltage of the card. This pin
is internally pulled high to the voltage
of the AuxVCC power pin under the
combined control of the external data
write bits and the CD pull up control
bits. This pin connects to PCMCIA
socket pin 57.
CardBus Voltage Sense: In CardBus
mode, these pins are the CVS2 pin.

of the socket (pins 17 and 51 of the
respective PCMCIA socket). These
pins can be 0, 3.3, or 5 V, depending
on card presence, card type, and
system configuration. The socket
interface outputs (listed in this table,
98, 60

A16,
F15
Table 2-2) will operate at the voltage
applied to these pins, independent of
the voltage applied to other OZ6833
pin groups.
1To differentiate the sockets in the pin diagram, all socket- specific pins have either A_ or B_ prefixes to the pin names indicated.
For example, A_A[25:0] and B_A[25:0] are the independent address buses to the sockets.
2When a socket is configured as an ATA drive interface, socket interface pin functions change.
