10.3.4 LVI Trip Selection
The LVI5OR3 bit in the configuration register selects whether the LVI is configured for 5-V or 3-V
protection.
10.4 LVI Status Register
The LVI status register (LVISR) indicates if the V
LVIOUT — LVI Output Bit
10.5 LVI Interrupts
The LVI module does not generate interrupt requests.
10.6 Low-Power Modes
The STOP and WAIT instructions put the MCU in low power-consumption standby modes.
10.6.1 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.
