IREQ
The value of RDY/BSC 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.
Indicates that the value of RDY/BSC 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/BSC 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 type.
