11.3.3
This LSI supports big endian and little endian as data alignment. Data alignment is determined by
the level of the external pin (MD5) at a power-on reset.

11.3.4
This LSI supports the PCMCIA interface specifications for areas 5 and 6 in the external memory
space.
The IC memory card interface and I/O card interface prescribed in JEIDA specifications version
4.2 (PCMCIA2.1) are supported.
Both the IC memory card interface and the I/O card interface are supported in areas 5 and 6 in the
external memory space.
The PCMCIA interface is only supported in little endian mode.
