7.5. Comparator Register Descriptions  
The SFRs used to enable and configure the comparators are described in the following register descrip-  
tions. A Comparator must be enabled by setting the CPnEN bit to logic 1 before it can be used. From an  
enabled state, a comparator can be disabled and placed in a low power state by clearing the CPnEN bit to  
logic 0.  
Important Note About Comparator Settings: False rising and falling edges can be detected by the Com-  
parator while powering on or if changes are made to the hysteresis or response time control bits. There-  
fore, it is recommended that the rising-edge and falling-edge flags be explicitly cleared to logic 0 a short  
time after the comparator is enabled or its mode bits have been changed. The Comparator Power Up Time  
is specified in Section “Table 4.13. Comparator Electrical Characteristics” on page 63.
