Figure 6-24 provides the PCMCIA access cycle timing for the external bus read.

Num
PSST = 1. Otherwise add PSST times cycle time.
PSHT = 0. Otherwise add PSHT times cycle time.
These synchronous timings define 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 2 cycles before the PSL timer expiration.
See PCMCIA Interface in the MPC850 PowerQUICC User’s Manual.
CLKOUT to ALE negate time
PCWE, IOWR negated to D[0–31]
invalid.
WAIT_B valid to CLKOUT rising edge.
CLKOUT rising edge to WAIT_B invalid.
