(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
The CnRVM register 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 the CnEN bit when the operation of the
