Bit
Bit Name Initial Value R/W Description
4
P0SC
0
R/W PCC0 Status Change
Indicates a change in the value of the STSCHG of the PC card
when the PC card connected to area 6 is the I/O card interface
type. When the STSCHG is changed from 1 to 0, the P0SC bit
is set to 1. When STSCHG is not changed, the P0SC bit
remains at 0. Write 0 to bit 4 when this bit is set to 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 IC memory card interface.
0: STSCHG of the PC card is not changed when the PC card
is on the I/O card interface
1: STSCHG of the PC card is changed from 1 to 0 when the
PC card is on the I/O card interface
3
P0CDC
0
R/W PCC0 Card Detect Change
Indicates a change in the value of the CD1 and CD2 in the PC
card connected to area 6. When the CD1 and CD2 values are
changed, the P0CDC bit is set to 1. When the values are not
changed, the P0CDC bit remains at 0. Write 0 to bit 3 in order
to clear this bit to 0. This bit is not changed if 1 is written.
0: CD1 and CD2 in the PC card are not changed
1: CD1 and CD2 in the PC card are changed
2
P0RC
0
R/W PCC0 Ready Change
Indicates a change in the value of the RDY/BSY of the PC
card when the PC card connected to area 6 is the IC memory
card interface type. When the RDY/BSY is changed from 0 to
1, the P0RC bit is set to 1. When the RDY/ BSY is not
changed, the P0RC bit remains at 0. Write 0 to bit 2 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: RDY/BSY in the PC card is not changed when the PC card
is on the IC memory card interface
1: RDY/BSY in the PC card is changed from 0 to 1 when the
PC card is on the IC memory card interface
