Low Voltage Inhibit (LVI)
14.4 LVI Control Register (CONFIG2/CONFIG1)
The LVI module is controlled by three bits in the configuration registers, CONFIG1 and CONFIG2.
LVID — Low Voltage Inhibit Disable Bit
LVIT1, LVIT0 — LVI Trip Voltage Selection
14.5 Low-Power Modes
The STOP and WAIT instructions put the MCU in low-power-consumption standby modes.
14.5.1 Wait Mode
The LVI module, when enabled, will continue to operate in WAIT Mode.
14.5.2 Stop Mode
The LVI module, when enabled, will continue to operate in STOP Mode.
128
These two bits determine at which level of V
are cleared by a Power-On Reset only.
1 = Low voltage inhibit disabled
0 = Low voltage inhibit enabled
