35.11 Power-on Reset Characteristics
Table 35-16. Power-on Reset Characteristics
Symbol Parameter
Condition
V_POT- ⁽¹⁾
POR threshold voltage falling V_CC
V_CC falls faster than 1V/ms
V_CC falls at 1V/ms or slower
V_POT+
POR threshold voltage rising V_CC
Note:
1. V_POT- values are only valid when BOD is disabled. When BOD is enabled V_POT- = V_POT+.
