Section 30 PC Card Controller (PCC)
Continuous 16-MB Area Mode: Setting 1 in bit 3 (P0MMOD) of the general control register
enables the continuous 16-MB area mode. In this mode, the attribute memory space and I/O
memory space are 16 MB, and the common memory space is 64 MB. In the common memory
space, set the PC card address in bit 2 (P0PA25) and bit 1 (P0PA24) of the general control register
to access an address of more than 16 MB. By this operation, values are output to A25 and A24
pins, enabling an address space of more than 16 MB to be accessed (initial value: 0 for P0PA25
and P0PA24). When an address of 16 MB or less is accessed, no settings are required. This bit
does not affect access to attribute memory space or I/O memory space.
Figure 30.3 shows the relationship between the memory space of the SH7727 and the memory and
I/O spaces of the PC card in the continuous 16-MB area mode. Although memory space and I/O
space are supported in area 6.
The attribute memory space, common memory space, and I/O space of the PC card are provided as
16-MB physical spaces in this mode. Therefore, the SH7727 automatically controls PCCREG pin
(the value of bit 0 (P0REG) in the general control register is ignored). In area 6, the output of
PCCREG pin is 0 when the attribute memory space or I/O space is accessed, and 1 when the
common memory space is accessed.
See the register descriptions in section 30.2, Register Descriptions for details of register settings.
