Master Clear (input) or programming voltage (input). This
pin is an active-low Reset to the device.
Oscillator crystal or external clock input.
Oscillator crystal or clock output.
PORTA is a bidirectional I/O port.
Oscillator crystal input.
External clock source input. Always associated
with pin function OSC1. (See related OSC1/CLKI,
OSC2/CLKO pins.)
General purpose I/O pin.
Oscillator crystal output. Connects to crystal or
resonator in Crystal Oscillator mode.
In EC modes, OSC2 pin outputs CLKO, which has
1/4 the frequency of OSC1 and denotes the
instruction cycle rate.
General purpose I/O pin.
