Bus Signal Timing
Figure 9-24 provides the PCMCIA access cycle timing for the external bus read.
Figure 9-24. PCMCIA Access Cycles Timing External Bus Read
Figure 9-25 provides the PCMCIA access cycle timing for the external bus write.

PSST = 1. Otherwise add PSST times cycle time.
PSHT = 0. Otherwise add PSHT times cycle time.
These synchronous timings define when the WAITx signals are detected in order to freeze
(or relieve) the PCMCIA current cycle. The WAITx assertion will be effective only if it is
detected 2 cycles before the PSL timer expiration. See PCMCIA Interface in the
