NOTE:
The LVI status register flags V
LVIOUT — LVI Output Bit
LOWV— LVI Low Indicator Bit
The LVI module does not generate CPU interrupt requests.
The STOP and WAIT instructions put the MCU in low power-consumption standby
modes.
The LVI module remains active in wait mode. The LVI module can generate a reset
if a V
The LVI can be enabled or disabled in stop mode by setting the LVISTOP bit in the
CONFIG register. (See
To minimize STOP I
Address: $FE0F
The read-only flag becomes set when the V
