25.3.2
Activation (ON) and deactivation (OFF) of the Battery Level Detector are controlled by setting the ENBL bit of the
Battery Level Detector control register (BLDCON1), and the result of the comparison of the power supply voltage
(VDD) to the threshold voltage is output to the BLDF bit of BLDCON1.
When ENBL, the enable control bit of the Battery Level Detector, is set to “1”, the detector is activated (ON). When
ENBL is set to “0”, the detector is deactivated (OFF) and has no supply current.
BLDF indicates the result of comparison. When BLDF bit is set to “1”, it indicates the power supply voltage is lower
than the threshold voltage. When BLDF bit is set to “0”, it indicates the power supply voltage (VDD) is higher than the
threshold voltage. The Battery Level Detector requires a settling time. Read BLDF bit 1ms or more after ENBL bit is
set to “1”.
Figure 25-2 shows an example of the operation timing diagram.
The operations in Figure 28-2 are described below.
Note:
Select the threshold voltage (VCMP) when the ENBL bit is “0”.
Threshold voltage
1 The Battery Level Detector is activated (ON) by setting the ENBL bit to “1”.
2 Wait the settling time (min. 1 ms) of the Battery Level Detector.
3 Read BLDF bit.
4 Set ENBL bit to “0”.
