18.2 Introduction
This section describes the low-voltage inhibit module (LVI47, Version A),
which monitors the voltage on the V_DD pin and can force a reset when
the V_DD voltage falls to the LVI trip voltage.
18.3 Features
Features of the LVI module include:
• Programmable LVI Reset
• Programmable Power Consumption
• Digital Filtering of V_DD pin level
