14.2 Introduction
This section describes the low-voltage inhibit (LVI) module, which
monitors the voltage on the V
DD
pin and can force a reset when the V
DD
voltage falls below the LVI trip falling voltage, V
TRIPF
.
14.3 Features
Features of the LVI module include:
• Programmable LVI reset
• Selectable LVI trip voltage
• Programmable stop mode operation
