Low-Voltage Inhibit (LVI) Module
15.3 Features
15.4 Functional Description
Technical Data
Features of the LVI module include:

out of reset. The LVI module contains a bandgap reference circuit and
comparator. The LVI power bit, LVIPWR, enables the LVI to monitor V
voltage. The LVI reset bit, LVIRST, enables the LVI module to generate
a reset when V
below that level for nine or more consecutive CPU cycles. LVISTOP
enables the LVI module during stop mode. This will ensure when the
STOP instruction is implemented, and the LVI will continue to monitor
the voltage level on V
configuration register (CONFIG-1). See
