Note
TPW 300 μ s
Note Minimum time required for a POR reset when VDD exceeds below VPDR. This is also the minimum time required
for a POR reset from when VDD exceeds below 0.7 V to when VDD exceeds VPOR while STOP mode is entered or
the main system clock is stopped through setting bit 0 (HIOSTOP) and bit 7 (MSTOP) in the clock operation
status control register (CSC).
