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 MPC860
PowerQUICC User s Manual.
Figure 9-24 provides the PCMCIA access cycle timing for the 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.
