Note Minimum time required for a POR reset when V
DD exceeds below VPDR. This is also the minimum time required for a
POR reset from when V
DD 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).
