Flash wait state information is incorrect

Problem:

The Address-to-Data wait state and Recovery Cycle wait state fields in Table 275 (PBBAR0) and

Table 276 (PBBAR1) are incorrect.

Workaround:

The Address-to-Data wait states are defined in bits 4:2. The wait states are actually one more than

listed. Therefore the following change applies:

000 - 5 Address-to-Data wait states

001 - 9 Address-to-Data wait states

010 - 13 Address-to-Data wait states

011 - 17 Address-to-Data wait states

Others (default) - 21 Address-to-Data wait states

The Recovery Cycle wait states are defined in bits 8:6. The wait states are actually two more than

listed. Therefore the following change applies:

000 - 3 Recovery wait states

001 - 6 Recovery wait states

010 - 10 Recovery wait states

011 - 14 Recovery wait states

100 - 18 Recovery wait states

Others (default) - 22 Recovery wait states

This change also affects Table 271, Flash Wait State Profile Programming.
