out of reset. The LVI module contains independent bandgap reference
circuit and comparator for monitoring the V
voltage. An LVI reset performs a MCU internal reset and drives the RST
pin low to provide low-voltage protection to external peripheral devices.

output of the comparator controls the state of the LVIOUT flag in the LVI
status register (LVISR).
An LVI reset also drives the RST pin low to provide low-voltage
protection to external peripheral devices.
