2 PCC1 Ready Change (P1RC)
If this bit is high: Indicates that pin READY in the PC card is changed from 0 to 1 when the
PC card is in the IC memory card interface.
If this bit is low: Indicates that pin READY in the PC card is not changed when the PC
card is in the IC memory card interface. (Initial value)

bit, 0 is always read in the I/O and Memory card interface.
1 PCC1 Battery Warning (P1BW)
If this bit is high: Indicates that pins BVD2 and BVD1 in the PC card are in the battery
warning state that the battery must be replaced although the data integrity is guaranteed
when the PC card is in the IC memory card interface.
If this bit is low: Indicates that pins BVD2 and BVD1 in the PC card are not in the battery
warning state when the PC card is in the IC memory card interface. (Initial value)
This bit is updated when the BVD2 and BVD1 pins are changed. Write 0 to bit 2 in order to

0 PCC1 Battery Dead (P1BD)
If this bit is high: Indicates that pins BVD2 and BVD1 in the PC card are in the state that
the battery must be replaced since the data integrity is not guaranteed when the PC card
is in the IC memory card interface.
If this bit is low: Indicates that pins BVD2 and BVD1 in the PC card are not in the state
that the battery must be replaced since the data integrity is not guaranteed when the PC
card is in the IC memory card interface. (Initial value)
This bit is updated when the BVD2 and BVD1 pins are changed. Write 0 to bit 2 in order to
