Bit
Bit Name Initial Value R/W Description
3
P0CDC 0
R/W PCC0 Card Detect Change
Indicates a change in the value of the CD1 and CD2
pins 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 pins in the PC card are not changed
1: CD1 and CD2 pins in the PC card are changed
2
P0RC
0
R/W PCC0 Ready Change
Indicates a change in the value of the RDY/BSY pin of
the PC card when the PC card connected to area 6 is
the IC memory card interface type. When the
RDY/BSY pin is changed from 0 to 1, the P0RC bit is
set to 1. When the RDY/BSY pin 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 pin in the PC card is not changed when
the PC card is on the IC memory card interface
1: RDY/BSY pin in the PC card is changed from 0 to 1
when the PC card is on the IC memory card interface
