Section 30 PC Card Controller (PCC)
Bit 1—PC Card Address (P0PA24): Controls A24 pin for the PC card connected to area 6.
When bit P0MMOD is 1 and the common memory space is accessed for the PC card connected to
area 6, this bit is output to A24 pin. When bit P0MMOD is 0 or the attribute memory space or I/O
space is accessed, this bit is meaningless.

Description
When bit P0MMOD is 1 and the common memory space is accessed for the
PC card connected to area 6, 0 is output to A24 pin
(Initial value)
When bit P0MMOD is 1 and the common memory space is accessed for the
PC card connected to area 6, 1 is output to A24 pin
Bit 0—PCC0REG Space Indication (P0REG): Controls PCCREG pin for the PC card
connected to area 6. When bit P0MMOD is 0, this bit is output to PCCREG pin for the PC card
connected to area 6. When bit P0MMOD is 1 or the I/O card interface is accessed, this bit is
meaningless.
Bit 0: P0REG
0
1
Description
When bit P0MMOD is 0 and the PC card connected to area 6 is accessed, 0
is output to PCCREG pin
(Initial value)
When bit P0MMOD is 0 and the PC card connected to area 6 is accessed, 1
is output to PCCREG pin

The area 6 card status change register (PCC0CSCR) is an 8-bit readable/writable able register.
PCC0CSCR bits are set to 1 by interrupt sources of the PC card connected to area 6 (only bit 7 can
be set to 1 as required). PCC0CSCR is initialized by a power-on reset but retains its value in a
manual reset and in software standby mode.
