I
PC Card Detect 1 and Card Detect 2. CD1 and CD2 are connected to
ground internally on the PC Card. When a PC Card is inserted into a
socket, these signals are pulled low. The signal status is available by
reading the Interface Status Register
BVD1
(STSCHG/ 138
72
RI)
I
Battery Voltage Detect 1. Generated by 16-bit memory PC Cards that
include batteries. BVD1 is used with BVD2 as an indication of the
condition of the batteries on a memory PC Card. Both BVD1 and BVD2
are kept high when the battery is good. When BVD2 is low and BVD1 is
high, the battery is weak and needs to be replaced. When BVD1 is low,
the battery is no longer serviceable and the data in the memory PC
Card is lost. See the Card Status Change Interrupt Configuration
Register for enable bits (Section 8.6). See the Card Status Change
Register and the Interface Status Register for the status bits for this
signal.
Status Change. STSCHG is used to alert the system to a change in the
READY, Write Protect, or Battery Voltage Dead condition of a 16-bit I/O
PC Card.
Ring Indicate. RI is used by 1 6-bit modem cards to indicate ring
detection.
+
Terminal name is preceded with A_. As an example, the full name for terminal 121 is A_A25.
≠
Terminal name is preceded with B_. As an example, the full name for terminal 55 is B_A25.
