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 PIC18F65K22 and PIC18F85K22 devices.
4: PSP is available only in Microcontroller mode.
5: The CC6, CCP7, CCP8 and CCP9 pin placement depends on the setting of the ECCPMX Configuration bit
(CONFIG3H<1>).
