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
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
detect power-loss conditions, use a low-voltage inhibit module (LVI) or
other suitable circuit.
