Comparator Registers
There are four registers for overall comparator operation. The CP0CR and CP1CR registers are
used to control the respective comparators settings for the Comparator 0 and Comparator 1 while
the CPHCR register is used to manage the hysteresis selection for these two comparators. In
addition, the CPICR register control the comparators interrupt settings. The accompanying register
table illustrates the control registers list.
