Bi-directional I/O port/Oscillator crystal output. Connects  
to crystal or resonator in crystal oscillator mode. In ER  
mode, OSC2 pin outputs CLKOUT which has 1/4 the fre-  
quency of OSC1, and denotes the instruction cycle rate.

Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt.  
Note 2: This buffer is a Schmitt Trigger input when used in serial programming mode.  
Note 3: This buffer is a Schmitt Trigger I/O when used in USART/Synchronous mode.  
Note 4: This buffer is a Schmitt Trigger I/O when used in CCP mode.  
Note 5: This buffer is a Schmitt Trigger input when used in low voltage program mode.
