PSHT = 0. Otherwise add PSHT times cycle time.
These synchronous timings define when the WAITA signals are detected in order to freeze (or relieve) the PCMCIA current
cycle. The WAITA assertion is effective only if it is detected 2 cycles before the PSL timer expiration. See PCMCIA Interface
in the MPC852T PowerQUICC User s Manual.
PSST = 1. Otherwise add PSST times cycle time.
