Description
PCC0 Battery Warning
Indicates whether the BVD2 and BVD1 pins of the PC
card are in the state in which “the battery must be
changed although the data is guaranteed” when the PC
card connected to area 6 is on the IC memory card
interface. When the BVD2 and BVD1 pins are 0 and 1,
respectively, the P0BW bit is set to 1; in other cases,
the P0BW bit remains at 0. This bit is updated when
the BVD2 and BVD1 pins are changed. Write 0 to bit 1
in order to clear this bit to 0. This bit is not changed if 1
is written. This bit always reads 0 on the I/O card
interface.
0: BVD2 and BVD1 of the PC card are not in the battery
1: BVD2 and BVD1 of the PC card are in the battery
PCC0 Battery Dead
Indicates whether the BVD2 and BVD1 pins of the PC
card are in the state in which “the battery must be
changed since the data is not guaranteed” when the PC
card connected to area 6 is on the IC memory card
interface. When the BVD2 and BVD1 pins are 1 and 0
or 0 and 0, the P0BD bit is set to 1; in other cases, the
P0BD bit remains at 0. This bit is updated when the
BVD2 and BVD1 pins are changed. Write 0 to bit 0 in
order to clear this bit to 0. This bit is not changed if 1 is
written. This bit always reads 0 on the I/O card
interface.
0: BVD2 and BVD1 of the PC card are not in the state
1: BVD2 and BVD1 of the PC card are in the state in
warning state when the PC card is in the IC memory
card interface
warning state and “the battery must be changed
although the data is guaranteed” when the PC card
is on the IC memory card interface
in which “the battery must be changed since the data
is not guaranteed” when the PC card is on the IC
memory card interface
which “the battery must be changed since the data is
not guaranteed” when the PC card is on the IC
memory card interface
