Note 1: Default assignment for ECCP2 when the CCP2MX Configuration bit is set.
2: Alternate assignment for ECCP2 when the CCP2MX Configuration bit is cleared.
3: Not available on PIC18F65K90 and PIC18F85K90 devices.
4: The CCP6, CCP7, CCP8 and CCP9 pin placement depends on the ECCPMX Configuration bit setting.
