(3) Comparator n control register (CnCTL)
This register is used to control the operation of comparator n, enable or disable comparator output, reverse the
output, and set the noise elimination width.
CnCTL can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
(Note, Caution, and Remark are listed on the next page.)
