13. Bus State Controller (BSC)
When using the PCMCIA interface, set a bus width of 8 or 16 bits. For details, see section 13.3.7,
PCMCIA Interface.
For details, see section 13.2.2, Bus Control Register 2 (BCR2), and section 13.2.8, Memory
Control Register (MCR).
The area 7 address range, H'1C000000 to H'1FFFFFFFF, is a reserved space and must not be used.
13.1.6
This LSI supports PCMCIA 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.
