Description
PCC0 Battery Warning
Indicates whether the BVD2 and BVD1 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
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 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 warning
PCC0 Battery Dead
Indicates whether the BVD2 and BVD1 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 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 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.
