Technical Data
244
One-time writable register after each reset. URSTD and LVID bits are reset by POR or LVI reset only.
Address:
LVID —þLow Voltage Inhibit Disable Bit
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.
