Setting procedure to generate a reset
Note 1: The VDCR1 and VDCR2 are only initialized by a power-on reset or an external reset input. Therefore, at the
Note 2: The voltage detect reset signal remains asserted while the supply voltage (VDD) is below the threshold
To disable the voltage detection circuit while it is enabled with the voltage detection interrupt request, make
The following shows the setting procedure for generating a voltage detect x reset signal upon detection of a
To disable the voltage detection circuit while it is enabled with the voltage detection reset, make the following
Note:If the voltage detection circuit is disabled without clearing interrupt enable flag, unexpected interrupt
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. Clear VDCR2<VDxEN> to 0 to disable the voltage detection operation.
1. Clear the INTVLTD interrupt enable flag <EF4> to 0.
2. Select the threshold 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 us until the voltage detecting circuit stabilizes.
6. Ensure that the VDCR1<VDxSF> bit is 0.
7. Clear VDCR1<VDxF> to 0.
8. Set the VDCR2<VDxMOD> bit to 1 to generate a voltage detect x reset signal upon detection of a low-
1. Clear the INTVLTD interrupt enable flag <EF4> to 0.
2. Clear VDCR2<VDxMOD> to 0 to set the operation mode to generate voltage detection interrupt request
3. Clear VDCR2<VDxEN> to 0 to disable the voltage detection operation.
