Low-Voltage Inhibit (LVI)
LVIIF — LVI Interrupt Flag
This clearable, read-only flag is set whenever the LVIOUT bit toggles. Reset clears the LVIIF bit.
1 = LVIOUT has toggled
0 = LVIOUT has not toggled
LVIIACK — LVI Interrupt Acknowledge Bit
Writing a logic 1 to this write-only bit clears the LVI interrupt flag, LVIIF. LVIIACK always reads as logic
0.
1 = Clears LVIIF bit
0 = No effect
13.5 Low-Power Modes
The STOP and WAIT instructions put the MCU in low power-consumption standby modes.
13.5.1 Wait Mode
If enabled, the LVI module remains active in wait mode. If enabled to generate resets or interrupts, the
LVI module can generate a reset or an interrupt and bring the MCU out of wait mode.
13.5.2 Stop Mode
If enabled in stop mode (LVISTOP = 1), the LVI module remains active in stop mode. If enabled to
generate resets or interrupts, the LVI module can generate a reset or an interrupt and bring the MCU out
of stop mode.
NOTE
If enabled to generate both resets and interrupts, there will be no LVI
interrupts, as resets have a higher priority.
