Section 29 PC Card Controller (PCC)
Bit
Bit Name Initial Value R/W Description
4
P0USE 0
R/W PCC0 Use/Not Use
Specifies that the PC Card Controller to be worked or
not worked.
0: PC Card Controller doesn't work
1: PC Card Controller works
Note:
When setting P0USE to 1, following settings are
required.
When P0USE is set to 1 and P0PCCT is set to
0, bits 21 and 20 (SA1 and SA0) in the
CS6BWCR register of BSC should be set to 0.
When P0USE and P0PCCT are set to 1, bits 21
and 20 (SA1 and SA0) in the CS6BWCR
register of BSC should be set to 1.
Before P0USE is set to 1, bits 15 to 12 (TYPE3
to TYPE0) in CS6BBCR of BSC should be set to
0101.

P0MMOD 0
R/W PCC0 Mode
Controls PCC_REG and A24 pins for the PC card
connected to area 6. Specifies either A24 of the
address to be accessed or bit P0REG for outputting to
PCC_REG pin. When the common memory space is
accessed, specifies either A24 of the address to be
accessed or bit P0PA24 for outputting to A24 pin. By
this operation, continuous 32 or 16 Mbytes can be
selected for the address area of the common memory
space of the PC card.
0: Bit P0REG is output to PCC_REG pin, and A24 of
address to be accessed is output to A24 pin
(continuous 32-Mbyte area mode)
1: A24 of address to be accessed is output to
PCC_REG pin. When the common memory space is
accessed, P0PA24 is output to A24 pin (continuous
16-Mbyte area mode)
