Bit Name Description
7 P0RDY/ PCC0 Ready
IREQ _{The value on the RDY/BSY pin of the PC card}
connected to area 6 is read when the IC memory
card interface is connected. The value of IREQ pin
of the PC card connected to area 6 is read when
the I/O card interface is connected. This bit cannot
be written to.
0: Indicates that the value of RDY/BSY is 0 when
the PC card connected to area 6 is an IC
memory card interface type. The value of
RDY/BSY is 0 when the PC card connected to
area 6 is the I/O card interface type.
1: Indicates that the value of PCC_RDY (IREQ) is 1
when the PC card connected to area 6 is the IC
memory card interface type. The value of
PCC_RDY (IREQ) is 1 when the PC card
connected to area 6 is the I/O card interface type.
6 P0MWP PCC0 Write Protect
The value of WP of the PC card connected to area
6 is read when the IC memory card interface is
connected. 0 is read when the I/O card interface is
connected. This bit cannot be written to.
0: Indicates that the value of WP is 0 when the PC
card connected to area 6 uses the IC memory
card interface type. The value of bit 6 is always 0
when the PC card connected to area 6 is the I/O
card interface type.
1: Indicates that the value of WP is 1 when the PC
card connected to area 6 is the IC memory card
interface type.
