This section describes the power-on reset (POR) module.
The POR module provides a known, stable signal to the MCU at
power-on. This signal tracks V
signal to indicate that it is properly initialized. At this time, the POR drives
its output low. The POR is not a brown-out detector, low-voltage
detector, or glitch detector. V
reset the MCU. To detect power-loss conditions, use a low-voltage
inhibit module (LVI) or other suitable circuit.
