NOTES:
NOTE:
1. The VC13 bit is enabled when the VC27 bit in the VCR2 register is set to 1 (Vdet4 detection function used).
1. Set the VCR2 register after the PRC3 bit in the PRCR register is set to 1 (write enable).
2. To use the hardware reset 2 (Vdet3 detection function), set the VC26 bit to 1.
3. To use the Vdet4 detection function, set the VC27 bit to 1 and the D40 bit in the D4INT register to 1 (Vdet4 detection interrupt
4. After the VC26 or VC27 bit is set to 1, the detection circuit waits for td(E-A) to elapse before starting operation.
5. The VC26 bit is disabled when the MCU is in stop mode. (The hardware reset 2 is not performed even if the voltage applied to
