Pin Name
To differentiate the sockets in the pin diagram, all socket-specific pins have either A_ or B_ prepended to the pin names indi-
cated. For example, A_A[25:0] and B_A[25:0] are the independent address buses to the sockets.
When a socket is configured as an ATA drive interface, socket interface pin functions change. See

Change / Ring Indicate: In Memory Card
Interface mode, this input serves as the
BVD1 (battery-dead status) input. In I/O
Card Interface mode, this input is the
-STSCHG input, which indicates to the
CL-PD6833 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 manage-
ment support.
In CardBus mode, this pin is the CardBus
Status Change used by the card to alert
the system to changes in READY, WP, and
BVD[2:1].
Voltage Sense 2: This pin is used in
conjunction with VS1 to determine the
operating voltage of the card. This pin is
internally pulled high to the voltage of the
+5V power pin under the combined control
of the external data write bits and the CD
pull-up control bits. This pin connects to
PC Card 16 socket pin 57.
In CardBus mode, this is CardBus Voltage
Sense 2. It is used in conjunction with
CVS1, CCD1, and CCD2 to determine the
initial voltage applied to the CardBus PC
Card.
Voltage Sense 1: This pin is used in con-
junction with VS2 to determine the operat-
ing voltage of the card. This pin is inter-
nally pulled high to the voltage of the +5V
power pin under the combined control of
the external data write bits and the CD
pull-up control bits. This pin connects to
PC Card 16 socket pin 43.
In CardBus mode, this is CardBus Voltage
Sense 1. It is used in conjunction with
CVS2, CCD1, and CCD2 to determine the
initial voltage applied to the CardBus PC
Card.
