16.2 Introduction
This section describes the low-voltage inhibit module (LVI), which
monitors the voltage on the V_DD pin and generates a reset when the V_DD
voltage falls to the LVI trip (LVI_TRIP) voltage.
16.3 Features
Features of the LVI module include the following:
• Selectable LVI trip voltage
• Selectable LVI circuit disable
