• Description: Renesas 32-Bit RISC Microcomputer Super RISC engine Family/SH7700 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

Figure 8.31 shows an example of PCMCIA card connection to this LSI. 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 this LSI 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 this LSI in big-endian mode is stipulated independently.
However, the WAIT signal is ignored in the following cases:
Rev. 4.00, 03/04, page 230 of 660
In 16-byte DMA transfer or dual addressing mode, or when writing data to the external address
area
In 16-byte DMA transfer or single addressing mode, or when transferring data from an
external device with DACK to the external bus area
When accessing cache for write back
32-Mbyte capacity (REG = I/O port)
Up to 16-Mbyte capacity (REG = A24)
