22.3 Description of Operation
VLS0 can be used to verify if V
DD
is lower or higher than the specified threshold voltage. In addition, by using VLS0, a
VLS0 interrupt can be generated when V
DD
is lower than the threshold voltage, or a VLS0 reset can be generated.
VLS0 has hysteresis characteristics. See the data sheet of each product for characteristics of the threshold voltage at
power voltage fall/rise.
The following two operation modes are available for VLS0:
Supervisor mode:
"1" is written to VLS0EN to enable operation of VLS0 to execute detecting the voltage. The result is notified of
through the VLS0RF flag as at the time the detection result becomes valid. The detection still continues.
By enabling generation of the VLS0 interrupt or VLS0 reset, the power supply voltage can be constantly
supervised so that the interrupt or reset can be generated whenever the power voltage becomes lower than the
threshold voltage.
Single mode:
"1" is written to VLS0EN to enable operation of VLS0 to execute detecting the voltage. "0" is automatically
written to VLS0EN to end the detection when the detection result becomes valid.
By enabling generation of the VLS0 interrupt, in single mode 1, the interrupt can be generated at the time of
completion of the voltage detection regardless of the result. In single mode 2, the interrupt (low voltage) can be
generated at the time of completion of the voltage detection whenever the power voltage is lower than the
threshold voltage.
