Master Clear (Reset) input. This pin is an active-low
Reset to the device.
OSC1/CLKI
OSC1
CLKI
13 32 30
Oscillator crystal or external clock input.
I
—
Oscillator crystal input or external clock source input.
I CMOS External clock source input. Always associated with
pin function OSC1. See related OSC2/CLKO pins.
OSC2/CLKO

14 33 31
O
O
Oscillator crystal or clock output.
—
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.
Legend: TTL = TTL compatible input
ST = Schmitt Trigger input with CMOS levels
O = Output
CMOS = CMOS compatible input or output
I
= Input
P
= Power
Note 1: Default assignment for CCP2 when configuration bit CCP2MX is set.
2: Alternate assignment for CCP2 when configuration bit CCP2MX is cleared.
