Compare Mode
In Compare mode, the 16-bit CCPRx register value is constantly compared against the TMR1
register pair value. When a match occurs, the CCPx pin is:
• Driven High
• Driven Low
• Remains Unchanged
The action on the pin is based on the value of control bits CCPxM3:CCPxM0 (CCPxCON<3:0>).
At the same time, a compare interrupt is also generated.

Note:
Timer1 must be running in Timer mode or Synchronized Counter mode if the CCP
module is using the compare feature. In Asynchronous Counter mode, the compare
operation may not work.
