Comparators
Reading Comparator Outputs
13.4 Reading Comparator Outputs
The state of each comparator output bit is internally readable from the
CMPCSR.
13.5 Comparator During Wait Mode
The comparator operates normally in wait mode. If the user wishes to
save power during the wait mode, the CEN1, CEN2, and CEN3 bits
should be cleared before the WAIT instruction.
13.6 Comparator During Stop Mode
Stop mode does not affect the comparator circuit. If the user needs to
save power, the CEN1, CEN2, and CEN3 bits should be cleared before
the STOP instruction.
13.7 Comparator Power Supply Source
The comparators are supplied by V_DD2 and V_SS2. These power lines are
reserved for noise-susceptible circuitry, such as the circuitry found in the
comparators.
