Setting Procedure for Generate an interrupt
The following shows the setting procedure for generating an INTVLTD interrupt upon detection of a low-
To disable the voltage detection circuit while it is enabled with the voltage detection interrupt request, make
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 INTVLTD interrupt enable flag <EF4> to 0.
2. Select the detection voltage by programming the VDCR1<VDxLVL> (x=1, 2) bits.
3. Clear the VDCR2<VDxMOD> bit to 0 to generate an INTVLTD interrupt upon detection of a low-
4. Set the VDCR2<VDxEN> bit to 1 to enable voltage detect operation.
5. Wait for 5 μs until the voltage detecting circuit stabilizes.
6. Ensure that the VDCR1<VDxSF> is 0.
7. Clear VDCR1<VDxF> to 0.
8. Clear the INTVLTD interrupt latch <IL4> to 0 and set the interrupt enable flag <EF4> to 1 to enable
1. Clear the INTVLTD interrupt enable flag <EF4> to 0.
2. Clear VDCR2<VDxEN> to 0 to disable the voltage detection operation.
