14.3.4 LVI Trip Selection
The LVI5OR3 bit in the configuration register selects whether the LVI is configured for 5V or 3V protection.
14.4 LVI Status Register
The LVI status register (LVISR) indicates if the V
LVIOUT — LVI Output Bit
14.5 LVI Interrupts
The LVI module does not generate interrupt requests.
14.6 Low-Power Modes
The STOP and WAIT instructions put the MCU in low power-consumption standby modes.
14.6.1 Wait Mode
If enabled, the LVI module remains active in wait mode. If enabled to generate resets, the LVI module can
generate a reset and bring the MCU out of wait mode.
14.6.2 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.
