PSST = 1. Otherwise add PSST times cycle time.
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 will be effective only if it is detected 2 cycles before the PSL timer expiration. See Chapter 16,
“PCMCIA Interface,” in the MPC885 PowerQUICC™ Family Reference Manual .
