Section 11 Local Bus State Controller (LBSC)
11.5.5
Areas 5 and 6 can be set to the IC memory card interface or I/O card interface, which is stipulated
in JEIDA specification version 4.2 (PCMCIA 2.1), by setting bits TYPE[2:0] in CS5BCR and
CS6BCR.
Figure 11.15 shows an example of PCMCIA card connection to this LSI. To enable hot insertion
of PCMCIA cards (i.e., insertion or removal while system power is being supplied), a three-state
buffer must be connected between this LSI bus interface and the PCMCIA cards.
Since operation in big-endian mode is not explicitly stipulated in the JEIDA/PCMCIA standard,
this LSI supports the PCMCIA interface only in little-endian mode through little-endian mode
setting.
PCMCIA interface can select space property from among 8-bit common memory, 16-bit common
memory, 8-bit attribute memory, 16-bit attribute memory, 8-bit I/O space, 16-bit I/O space,
dynamic I/O bus sizing, and ATA complement mode by setting bits SAA[2:0] and SAB[2:0] in
CSnPCR.
