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 the PCMCIA Interface section in the MPC866 PowerQUICC™ Family Reference
Manual.
