4:

Default assignment for ECCP2 when the CCP2MX Configuration bit is set.

Alternate assignment for ECCP2 when the CCP2MX Configuration bit is cleared.

Not available on PIC18F65K22 and PIC18F85K22 devices.

The CC6, CCP7, CCP8 and CCP9 pin placement depends on the setting of the ECCPMX Configuration bit

(CONFIG3H<1>).
