When the operation mode is set to generate voltage detection reset signals, make the following setting:
To disable the voltage detection circuit while it is enabled with the voltage detection reset, make the following
Note:When the supply voltage (VDD) is close to the detection voltage (VDxLVL), voltage detection request
Note:If the voltage detection circuit is disabled without clearing interrupt enable flag, unexpected interrupt
1. Clear the voltage detection circuit interrupt enable flag to "0".
2. Set the detection voltage at VDCR1<VDxLVL>(x=1 to 2).
3. Clear VDCR2<VDxMOD> to "0" to set the operation mode to generate INTVLTD interrupt request
4. Set VDCR2<VDxEN> to "1" to enable the voltage detection operation.
5. Wait for 5 [μs] or more until the voltage detection circuit becomes stable.
6. Make sure that VDCR1<VDxSF> is "0".
7. Clear the voltage detection circuit interrupt latch to "0" and set the interrupt enable flag to "1" to enable
1. Clear the voltage detection circuit interrupt enable flag to "0".
