LVI: Low-Voltage Interrupt

The low voltage interrupt (LVI) circuit monitors the operating voltage of the MCU and generates an interrupt to the MCU if the voltage drops below a predefined minimum. MCUs can continue to operate below the specified minimum voltage rating but may experience unpredictable operation before they fail. The LVI circuit generates an interrupt where software can cause an orderly shutdown before unpredictable behavior can occur.

LVPI: Low Voltage Program Inhibit

The low voltage program inhibit (LVPI) circuit monitors the operating voltage of the MCU and inhibits programming of the MCU if the voltage drops below a predefined minimum. MCUs can continue to program below the specified minimum voltage rating but may experience unpredictable operation before programming fails. The LVPI circuit inhibits programming before any unpredictable behavior can occur.

LVR: Low Voltage Reset

The low voltage reset (LVR) circuit monitors the operating voltage of the MCU and forces a reset of the MCU if the voltage drops below a predefined minimum. MCUs can continue to operate below the specified minimum voltage rating but may experience unpredictable operation before they fail. The LVR circuit places the MCU in the reset state before any unpredictable behavior can occur.
