Overview
The following resets are implemented: RES# pin reset, power-on reset, voltage monitoring 0 reset, voltage monitoring 1
reset, voltage monitoring 2 reset, independent watchdog timer reset, and software reset.
lists the reset names and sources.
Note 1. For the voltages to be monitored (VPOR, Vdet0, Vdet1, and Vdet2), see section 8, Voltage Detection Circuit (LVDAb) and
section 32, Electrical Characteristics.

Reset Names and Sources
Reset Name
Source
RES# pin reset
Voltage input to the RES# pin is driven low.
Power-on reset
VCC rises (voltage monitored: VPOR)
Voltage monitoring 0 reset
VCC falls (voltage monitored: Vdet0)
Voltage monitoring 1 reset
VCC falls (voltage monitored: Vdet1)
Voltage monitoring 2 reset
VCC falls (voltage monitored: Vdet2)
Independent watchdog timer reset
The independent watchdog timer underflows, or a refresh error occurs.
Software reset
