Low-Voltage Inhibit (LVI)
LVISTOP, LVIPWRD, LVI5OR3, and LVIRSTD are in the configuration register (CONFIG1). See

and the LVI. The output of the comparator controls the state of the LVIOUT flag in the LVI status register
(LVISR).
An LVI reset also drives the RST pin low to provide low-voltage protection to external peripheral devices.
11.3.1 Polled LVI Operation
In applications that can operate at V
the LVIOUT bit. In the configuration register, the LVIPWRD bit must be 0 to enable the LVI module, and
the LVIRSTD bit must be 1 to disable LVI resets.
11.3.2 Forced Reset Operation
In applications that require V
module to reset the MCU when V
LVIPWRD and LVIRSTD bits must be cleared to enable the LVI module and to enable LVI resets.
