22.2.1 Capture Sources

In Capture mode, the CCPx pin may be configured as an input by setting the associated TRIS control bit.

Important: If the CCPx pin is configured as an output, a write to the port can cause a Capture condition.

The capture source is selected by configuring the CTS bits as shown in the following table:

Table 22-2. Capture Trigger Sources
CTS	Source
`11`	IOC Interrupt
`10`	CMP2_output
`01`	CMP1_output
`00`	Pin selected by CCPxPPS
