For some microcontrollers oscillator input pins can also be used as digital input/out-
put pins. In order to implement this feature EasyPIC4 has jumpers for connecting
MCU either to oscillator or to digital I/O pins. You can see the schematics for OSC1
oscillator on Fig. 16.

Oscillator connection with MCU
Note:
If the used DIP’s oscillator pins are labeled with OSC1 then the oscillator
should be placed in the OSC1 connector. If the used DIP’s oscillator pins are labeled
with OSC2 then the oscillator should be placed in the OSC2 connector.
