Speaker Output: This output can be
used as a digital output to a speaker to
allow a system to support PC Card
fax/modem/voice and audio sound
output. This output is enabled by setting
the socket’s Misc Control 1 register bit 4
to “1” (for the socket whose speaker
signal is to be directed from BVD2/-
SPKR/-Led to this pin).
LED Output/SKTA_ACTV: This output
can be used as an LED driver to indicate
disk activity when a socket’s BVD2/-
SPKR/-LED pin has been programmed
for LED support.
In the O2 Mode(Index 3B/7B bit 5) , this
pin indicates the socket A activity. The
socket B activity refers to PCI
Configuration Register offset 90h (Mux
Control register)
Card Power Clock: This input is used as
a reference clock (10-100 kHz, usually
32 kHz) to control the serial interface of
the socket power control chips.
A_VCC5#: This active-LOW output
controls the 5 -volt supply to the A
socket’s VCC pins. The active-LOW
level of this output is mutually exclusive
with that of A_VCC3#.
Card Power Serial Data: This pin
serves as output DATA pin when used
with the serial interface of Texas
Instruments’ TPS2206IDF & Micrel 2564
socket power control chip.
B_VCC3#: This active-LOW output
controls the 3.3-volt supply to the A
socket’s VCC pins. The active-LOW
level of this output is mutually exclusive
with that of B_VCC5#.
Card Power Serial Latch: This pin
serves as output LATCH pin when used
with the serial interface of Texas
Instruments’ TPS2206IDF & Micrel 2564
socket power control chip.
B_VCC5#: This active-LOW output
controls the 5 -volt supply to the A
socket’s VCC pins. The active-LOW
level of this output is mutually exclusive
with that of B_VCC3#.
