(4) Comparator n internal reference voltage selection register (CnRVM)
This register is used to set the internal reference voltage of comparator n. The internal reference voltage can
be selected from six voltages that use AV
CnRVM can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Cautions 1. The operation of the comparator is controlled by CnEN when the operation of the internal

3. Set the reference voltage before enabling the operation of the internal reference voltage
4. Be sure to change the CnRVM register while CnEN = 0 (comparator operation stopped).
2. The negative-side external pin input of the comparator will be cutoff when CnVRE is set
