Bit 7
In Memory Card Interface mode, this bit is set to a ‘1’ when the BVD1/-STSCHG/-RI pin (see
Table
this bit is set to a ‘1’ when the BVD1/-STSCHG/-RI pin changes from either high to low or low to
high. In I/O Card Interface mode, the function of this bit is not affected by bit 7 of the Interrupt
and General Control register. This bit is reset to a ‘0’ whenever this register is read.
Bit 1: Battery Warning Change
In Memory Card Interface mode, this bit is set to a ‘1’ when the BVD2/-SPKR/-LED pin changes
from high to low, indicating a battery warning. This bit is not valid in I/O Card Interface mode.
This bit is reset to a ‘0’ whenever this register is read.
Bit 2: Ready Change
In Memory Card Interface mode, this bit is a ‘1’ when a change has occurred on the RDY/-IREQ
pin (see
whenever this register is read.
Bit 3: Card Detect Change
This bit is set to a ‘1’ when a change has occurred on the -CD1 or -CD2 pin (see
is reset to a ‘0’ whenever this register is read.
