5.6 Wait States Required
Figure 5-1. Wait States Scheme
As shown in the figure above, the TCM RAM can support program and data fetches at full CPU speed without
any address or data wait states required.
The TCM flash can support zero address and data wait states up to a CPU speed of 55 MHz in nonpipelined
mode. The flash supports a maximum CPU clock speed of 220 MHz in pipelined mode with one address wait
state and three data wait states.
The flash wrapper defaults to non-pipelined mode with zero address wait state and one random-read data wait
state.
