Master Clear (input) or programming voltage (input).
I
ST
Master Clear (Reset) input. This pin is an active-low
Reset to the device.
P
Programming voltage input.
I

Oscillator crystal or external clock input.
I
ST
Oscillator crystal input or external clock source input.
ST buffer when configured in RC mode;
analog otherwise.
I CMOS External clock source input. Always associated with
pin function OSC1. (See related OSC1/CLKI,
OSC2/CLKO pins.)
I/O TTL General purpose I/O pin.
OSC2/CLKO/RA6

Oscillator crystal or clock output.
O
—
Oscillator crystal output. Connects to crystal
or resonator in Crystal Oscillator mode.
O
—
In RC mode, OSC2 pin outputs CLKO, which
has 1/4 the frequency of OSC1 and denotes
the instruction cycle rate.
I/O TTL General purpose I/O pin.
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 assignment for CCP2 when Configuration bit, CCP2MX, is set.
2: Alternate assignment for CCP2 when Configuration bit, CCP2MX, is cleared.
