11.3.6
In the SH7729R, setting the A5PCM bit in BCR1 to 1 makes the bus interface for physical space
area 5 an IC memory card and I/O card interface as stipulated in JEIDA version 4.2
(PCMCIA2.1). Setting the A6PCM bit to 1 makes the bus interface for physical space area 6 an IC
memory card and I/O card interface as stipulated in JEIDA version 4.2.
When the PCMCIA interface is used, a bus size of 8 or 16 bits can be set by bits A5SZ1 and
A5SZ0, or A6SZ1 and A6SZ0, in BCR2.
Figure 11.31 shows an example of PCMCIA card connection to the SH7729R. To enable active
insertion of the PCMCIA cards (i.e. insertion or removal while system power is being supplied), a
3-state buffer must be connected between the SH7729R’s bus interface and the PCMCIA cards.
As operation in big-endian mode is not explicitly stipulated in the JEIDA/PCMCIA specifications,
the PCMCIA interface for the SH7729R in big-endian mode is stipulated independently.
However, the WAIT signal is ignored in the following three cases:
