Description
MCLR
MCLR
1 26
Master Clear (input) or programming voltage (input).
I ST
Master Clear (Reset) input. This pin is an active-low
Reset to the device.
OSC1/CLKI
OSC1
CLKI
9
6
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
OSC2
CLKO
10 7
Oscillator crystal or clock output.
O—
Oscillator crystal output. Connects to crystal or
resonator in Crystal Oscillator mode.
O—
In EC 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.
