Figure 9.42 shows the basic timing of the PCMCIA IC memory card interface. When areas 5 and 6

are specified as the PCMCIA interface, the bus is accessed with the IC memory card interface

according to the SA[1:0] bit settings in CS5WCR and CS6WCR. If the external bus frequency

(CKIO) increases, the setup times and hold times for the address pins (A25 to A0), card enable

signals (CE1A, CE2A, CE1B, CE2B), and write data (D15 to D0) to the RD and WE signals

become insufficient. To prevent this error, this LSI enables the setup times and hold times for

areas 5 and 6 to be specified independently, using CS5WCR and CS6WCR. In the PCMCIA

interface, as in the normal space interface, a software wait or hardware wait using the WAIT pin

can be inserted. Figure 9.43 shows the PCMCIA memory bus wait timing.
