Description
PCC0 Ready
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 pin is 0 when
1: Indicates that the value of RDY/BSY pin is 1 when
the PC card connected to area 6 is an IC memory
card interface type. The value of IREQ pin is 0 when
the PC card connected to area 6 is the I/O card
interface type.
the PC card connected to area 6 is the IC memory
card interface type. The value of IREQ pin is 1 when
the PC card connected to area 6 is the I/O card
interface type.
