Low-Voltage Inhibit (LVI)
LVIOUT — LVI Output Bit
This read-only flag becomes set when the V_DD voltage falls below the V_TRIPF
trip voltage (see Table 11-1). Reset clears the LVIOUT 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
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.
11.6.2 Stop Mode
If enabled in stop mode (LVISTOP 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.
