7.5.
The SFRs used to enable and configure the comparator are described in the following register
descriptions. The comparator must be enabled by setting the CP0EN 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
CP0EN bit to logic 0.
Important Note About Comparator Settings: False rising and falling edges can be detected by the
Comparator while powering on or if changes are made to the hysteresis or response time control bits.
Therefore, 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 4.14. Comparator Electrical Characteristics” on page 61.
