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.

signals may be generated frequently. If this may pose any problem, execute appropriate wait processing
depending on fluctuations in the system power supply and clear the interrupt latch before returning from
the INTVLTD interrupt service routine.
