(20) Comparator n control register 3 (CMPnCTL3)
Remark
The CMPnCTL3 register is a register that specifies the detection direction of the overvoltage detection
comparator and selects the edge detection.
This register can be read or written in 8-bit units.
Reset sets this register to 00H.
The reference value means the reference voltage input to the CREF0L and CREF0F pins.
