Low-Voltage Inhibit (LVI)
14.1 Introduction
This section describes the low-voltage inhibit module (LVI), which monitors the voltage on the V
and generates a reset when the V

LVI module should take actions.
The LVI module generates one output signal:
LVI Reset — an reset signal will be generated to reset the CPU when V
