When using the PCMCIA interface, set a bus width of 8 or 16 bits.
For details, see section 13.3.7, PCMCIA Interface.
When using port functions, set a bus width of 8, 16, or 32 bits for all areas.
For details, see section 13.2.2, Bus Control Register 2 (BCR2), and section 13.2.7, Memory
Control Register (MCR).
The area 7 address range, H'1C000000 to H'1FFFFFFFF, is a reserved space and must not be used.
Note: * SH7750R only
13.1.6
PCMCIA Support
The SH7750 Series supports PCMCIA compliant interface specifications for external memory
space areas 5 and 6.
The interfaces supported are the IC memory card interface and I/O card interface stipulated in
JEIDA specifications version 4.2 (PCMCIA2.1).
External memory space areas 5 and 6 support both the IC memory card interface and the I/O card
interface.
The PCMCIA interface is supported only in little-endian mode.
