Section 29
In area 6, set 1 in bit 0 (P0REG) of the general control register to access the common memory
space of the PC card, and set 0 in bit 0 to access the attribute memory space (initial value: 0). By
this operation, the set value is output to PCC_REG pin, enabling any space to be accessed. When
the I/O space is accessed in area 6, the output of PCC_REG pin is always 0 regardless of the value
of bit 0 (P0REG).
See the register descriptions in section 29.3, Register Descriptions for details of register settings.
