Low-Voltage Inhibit (LVI)
10.1 Introduction
The low-voltage inhibit (LVI) module is provided as a system protection mechanism to prevent the MCU
from operating below a certain operating supply voltage level. The module has several configuration
options to allow functionality to be tailored to different system level demands.
