Bus Signal Timing
Table 9

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 Chapter 16, “PCMCIA Interface,” in the MPC860 PowerQUICC™ Family
User’s Manual.
