7 RA6/CLKO/OSC2

RA6

I/O TTL Digital I/O.

CLKO

O

In RC mode, OSC2 pin outputs CLKOUT which has

1/4 the frequency of OSC1 and denotes the instruction

cycle rate.

OSC2

O

Oscillator crystal output. Connects to crystal or

resonator in Crystal Oscillator mode.

Legend: TTL = TTL compatible input CMOS = CMOS compatible input or output; ST = Schmitt Trigger input with CMOS levels;

I = Input; O = Output; P = Power.

Note 1: Default pin assignment for P2B, T3CKI, CCP3 and CCP2 when Configuration bits PB2MX, T3CMX, CCP3MX and

CCP2MX are set.

2: Alternate pin assignment for P2B, T3CKI, CCP3 and CCP2 when Configuration bits PB2MX, T3CMX, CCP3MX and

CCP2MX are clear.
