CLKI  
External clock source input. Always  
associated with pin function OSC1 (see  
OSC1/CLKI, OSC2/CLKO pins).

Oscillator crystal or clock output.  
O
O
Oscillator crystal output.  
Connects to crystal or resonator in  
Crystal Oscillator mode.  
In RC mode, OSC2 pin outputs CLKO,  
which has 1/4 the frequency of OSC1  
and denotes the instruction cycle rate.  
General purpose I/O pin.

Note 1: Alternate assignment for CCP2 when CCP2MX is not selected (all Operating modes except  
Microcontroller).  
2: Default assignment when CCP2MX is set.  
3: External memory interface functions are only available on PIC18F8X20 devices.  
4: CCP2 is multiplexed with this pin by default when configured in Microcontroller mode. Otherwise, it is  
multiplexed with either RB3 or RC1.  
5: PORTH and PORTJ are only available on PIC18F8X20 (80-pin) devices.  
6: AVDD must be connected to a positive supply and AVSS must be connected to a ground reference for proper  
operation of the part in User or ICSP modes. See parameter D001A for details.
