Table 31. Reset and Power-up AC Characteristics
Note: 1. The device Reset is possible but not guaranteed if t
PLPH
< 100ns.
2. Sampled only, not 100% tested.
3. It is important to assert RP in order to allow proper CPU initialization during Power-up or System reset.

Note: 1. Max values refer to the maximum time allowed by the internal algorithm before error bit is set. Worst case conditions program or
erase should perform significantly better.
2. Excludes the time needed to execute the sequence for program instruction.
3. Same timing value if V
