Section 30 PC Card Controller (PCC)

Bit 4âPCC0 Status Change (P0SC): Indicates a change in the value of the STSCHG pin of the

PC card when the PC card connected to area 6 is the I/O card interface type. When the STSCHG

pin is changed from 1 to 0, the P0SC bit is set to 1. When STSCHG pin is not changed, the P0SC

bit remains at 0. Write 0 to bit 4 when this bit is set to 1 in order to clear this bit to 0. This bit is

not changed if 1 is written. This bit always reads 0 on the IC memory card interface.

Bit 4: P0SC

Description

0

STSCHG pin of the PC card is not changed when the PC card is on the I/O

card interface

(Initial value)

1

STSCHG pin of the PC card is changed from 1 to 0 when the PC card is on

the I/O card interface

Bit 3âPCC0 Card Detect Change (P0CDC): Indicates a change in the value of the CD1 and

CD2 pins in the PC card connected to area 6. When the CD1 and CD2 values are changed, the

P0CDC bit is set to 1. When the values are not changed, the P0CDC bit remains at 0. Write 0 to

bit 3 in order to clear this bit to 0. This bit is not changed if 1 is written.

Bit 3: P0CDC

0

1

Description

CD1 and CD2 pins in the PC card are not changed

CD1 and CD2 pins in the PC card are changed

(Initial value)

Bit 2âPCC0 Ready Change (P0RC): Indicates a change in the value of the RDY/BSY pin of

the PC card when the PC card connected to area 6 is the IC memory card interface type. When the

RDY/BSY pin is changed from 0 to 1, the P0RC bit is set to 1. When the RDY/BSY pin is not

changed, the P0RC bit remains at 0. Write 0 to bit 2 in order to clear this bit to 0. This bit is not

changed if 1 is written. This bit always reads 0 on the I/O card interface.

Bit 2: P0RC

0

1

Description

RDY/BSY pin in the PC card is not changed when the PC card is on the IC

memory card interface

(Initial value)

RDY/BSY pin in the PC card is changed from 0 to 1 when the PC card is on

the IC memory card interface
