Low-Voltage Inhibit (LVI)

22.4.2 Forced Reset Operation
22.4.3 Voltage Hysteresis Protection
Data Sheet

In applications that can operate at V
software can monitor V
interrupt enable bit, LVIIE, to enable interrupt requests. In the
configuration register 1 (CONFIG1), the LVIPWRD bit must be at logic 0
to enable the LVI module, and the LVIRSTD bit must be at logic 1 to
disable LVI resets.
The LVI interrupt flag, LVIIF, is set whenever the LVIOUT bit changes
state (toggles). When LVIF is set, a CPU interrupt request is generated
if the LVIIE is also set. In the LVI interrupt service subroutine, LVIIF bit
can be cleared by writing a logic 1 to the LVI interrupt acknowledge bit,
LVIIACK.
In applications that require V
enabling LVI resets allows the LVI module to reset the MCU when V
falls below the V
the LVIPWRD and LVIRSTD bits must be at logic 0 to enable the LVI
module and to enable LVI resets.
If LVIIE is set to enable LVI interrupts when LVIRSTD is cleared, LVI
reset has a higher priority over LVI interrupt. In this case, when V
below the V
cleared.
