The area 6 interface status register (PCC0ISR) is an 8-bit read-only register which is used to read
the status of the PC card connected to area 6. The initial value of PCC0ISR depends on the PC
card status.
Bit 7—PCC0 Ready (P0RDY/IREQ): The value of 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.
Bit 7: P0RDY/IREQ

Description
Indicates that the value of RDY/BSY pin is 0 when the PC card connected to
area 6 is the IC memory card interface type. Indicates that the value of
IREQ pin is 0 when the PC card connected to area 6 is the I/O card interface
type
Indicates that the value of RDY/BSY pin is 1 when the PC card connected to
area 6 is the IC memory card interface type. Indicates that the value of
IREQ pin is 1 when the PC card connected to area 6 is the I/O card interface
