16.4 LVI Status Register
The LVI status register flags V
LVIOUT — LVI Output Bit
16.5 LVI Interrupts
The LVI module does not generate interrupt requests.
16.6 Low-Power Modes
The WAIT and STOP instructions put the MCU in low power-consumption standby modes.
16.6.1 Wait Mode
With the LVIPWR bit in the configuration register programmed to 1, the LVI module is active after a WAIT
instruction.
With the LVIRST bit in the configuration register programmed to 1, the LVI module can generate a reset
and bring the MCU out of wait mode.

This read-only flag becomes set when the V
