PSST = 1. Otherwise, add PSST times cycle time.
PSHT = 0. Otherwise, add PSHT times cycle time.
These synchronous timings deÞne when the WAIT_B signal is detected in order to freeze (or relieve) the
PCMCIA current cycle. The WAIT_B assertion will be effective only if it is detected two cycles before the PSL
timer expiration.
