Latest Updated:08/09/2007

Question:

(Reset)  When using the on-chip power-on reset circuit in the H version, what will happen if the time for the supply voltage to rise from 0V to the minimum voltage for recommended operating conditions exceeds the specified value? [2007/08/09]

Answer:

If internal reset signal is released before the supply voltage reaches the minimum voltage for recommended operating conditions, reset may fail.
In such instances, an external reset signal would be necessary. (#106697)
