Notes:
1. Select the voltage detection level with the VDSEL1 bit in the OFS1 address.
2. Necessary time until the voltage detector operates when setting to 1 again after setting the VC25 bit in the VCR2
register to 0.
3. Time from when passing the V_det0 until when a voltage monitor 0 reset is generated.
