Figure 16 Recovery from Wait/Stop State Using DR Pin — Asynchronous Timing

Capacitance Derating

The DSP56156 External Bus Timing Specifications are designed and tested at the maximum ca-

pacitive load of 50 pF, including stray capacitance. Typically, the drive capability of the Exter-

nal Bus pins (A0-A15, D0-D15, PS/DS, RD, BS, WR, R/W) derates linearly at 1 ns per 12 pF of

additional capacitance from 50 pF to 250 pF of loading. Port B and C pins derate linearly at 1 ns

per 5 pF of additional capacitance from 50 pF to 250 pF of loading.

When an internal memory access follows an external memory access, the PS/DS, R/W, RD

and WR strobes remain deasserted and A0-A15 do not change from their previous state.
