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 MPC866 PowerQUICC User’s Manual.
