Address:
LVID — Low Voltage Inhibit Disable Bit
LVIT1, LVIT0 — LVI Trip Voltage Selection
The STOP and WAIT instructions put the MCU in low-power-
consumption standby modes.
The LVI module, when enabled, will continue to operate in WAIT Mode.
The LVI module, when enabled, will continue to operate in STOP Mode.

Write:
These two bits determine at which level of V
come into action. LVIT1 and LVIT0 are cleared by a Power-On Reset
only.
