Section 29 PC Card Controller (PCC)
29.3 Register Descriptions
PCC has the following registers.
• Area 6 interface status register (PCC0ISR)
• Area 6 general control register (PCC0GCR)
• Area 6 card status change register (PCC0CSCR)
• Area 6 card status change interrupt enable register (PCC0CSCIER)
29.3.1 Area 6 Interface Status Register (PCC0ISR)
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
Bit Name Initial Value R/W Description
7
P0RDY/ Undefined* R 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 pin is 0 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.
1: 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. The value of IREQ pin is 1 when
the PC card connected to area 6 is the I/O card
interface type.
