11.4 LVI Status Register
The LVI status register (LVISR) indicates if the V
LVIOUT — LVI Output Bit
11.5 LVI Interrupts
The LVI module does not generate interrupt requests.
11.6 Low-Power Modes
The STOP and WAIT instructions put the MCU in low power-consumption standby modes.
11.6.1 Wait Mode
The LVI module remains active in wait mode. The LVI module will generate a reset and bring the MCU
out of wait mode.
11.6.2 Stop Mode
If enabled in stop mode (LVISTOP bit in the configuration register is set), the LVI module remains active
in stop mode. If enabled to generate resets, the LVI module can generate a reset and bring the MCU out
of stop mode.
