OZ6812
Pin Name
RESET/
CRST#
Description
Reset: This active high output resets the card.
To prevent reset glitches, 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.
BVD2/SPKR#/
LED / CAUDIO
CardBus Reset: In CardBus mode, this pin is
the CRST# output.
Battery Voltage Detect 2 / Speaker / LED: In
Memory mode, this input serves as the BVD2
(battery warning status) input. In I/O mode, this
input can be configured as the card’s SPKR#
audio input or drive-active LED input.
BVD1/
STSCHG#/RI#/
CSTSCHG
CardBus Audio: In CardBus mode, this pin is
the CAUDIO input.
Battery Voltage Detect 1 / Status Change /
Ring Indicate: In Memory mode, this is the
BVD1 (battery-dead status) input. In I/O mode,
this is the STSCHG# input indicating that the
card’s internal status has changed, or the ring
indicates input for wakeup-on-ring system
power management support. See bit 7 of the
Interrupt and General Control register (03h).
VS[2:1]/
CVS[2:1]
CardBus Status Change: In CardBus mode,
this pin is the CSTSCHG. This pin can be used
to generate PME#.
Voltage Sense: These pins are used in
conjunction with CD[2:1] to determine the type
and voltage of a card. These pins are internally
pulled high to AUX_VCC. See Table 1.
SOCKET_VCC
CardBus Voltage Sense: In CardBus mode,
these pins are the CVS[2:1] pins.
Socket Power: These pins are the power rail
input for the socket interface control logic.
These pins can be 0, 3.3, or 5 V,. The socket
interface outputs will operate at the voltage
applied to these pins.
