Section 9 Bus State Controller (BSC)

Figure 9.38 shows the basic timing of the PCMCIA IC memory card interface. If areas 5 and 6 in
the physical space are specified as the PCMCIA interface, accessing the common memory areas in
areas 5 and 6 automatically accesses the IC memory card interface. If the external bus frequency
(CKIO) increases, the setup times and hold times for the address pins (A25 to A0) to RD and WE,
card enable signals (CE1A, CE2A, CE1B, CE2B), and write data (D15 to D0) become
insufficient. To prevent this error, the LSI can specify the setup times and hold times for areas 5
and 6 in the physical space independently, using CS5BWCR and CS6BWCR. In the PCMCIA
interface, as in the normal space interface, a software wait or hardware wait can be inserted using
the WAIT pin. Figure 9.39 shows the PCMCIA memory bus wait timing.
