Section 30 PC Card Controller (PCC)
30.1.4 PCMCIA Support
The SH7727 supports an interface based on PCMCIA specifications for physical areas 6.
Interfaces supported are the IC memory card interface and I/O card interface defined in the
PCMCIA Rev. 2.1/JEIDA Ver. 4.2 standard. Both the IC memory card interface and I/O card
interface are supported in area 6.

Dynamic bus sizing for I/O bus width*
The PCMCIA interface can be accessed from the address-
conversion region and non-address-conversion region.
Note: * Dynamic bus sizing for the I/O bus width is supported only in little-endian mode.
The SH7727 can directly access 32- and 64-MB physical areas in a 64-MB memory space and an
I/O space of the PC card (continuous 32/16-MB area mode). The SH7727 provides a segment bit
(an address bit for the PC card) in the general control register for area 6 to support a common
memory space with full PCMCIA specifications (64 MB).
