BLDCON1 is a special function register (SFR) to control the Battery Level Detector.
[Description of Bits]
Initial value
BLDCON1
•
The ENBL bit is used to control activation (ON) or deactivation (OFF) of the Battery Level Detector.
The Battery Level Detector is activated (ON) and deactivated (OFF) by setting the ENBL bit to “1” and “0”,
respectively.
•
The BLDF bit is the judgment result flag of the Battery Level Detector.
The BLDF bit is set to “1” or “0” when the power supply voltage (VDD) is lower than or higher than the threshold
voltage selected by LD3 to LD0 bits of BLDCON0 register, respectively.
