INPUT
OUTPUT
Internal Oscillator Terminals.
Connects a device selected from the ceramic or the crystal
resonator, or the resistor, to these terminals for the internal
oscillator.
In the external clock operation, OSC1 is the external clock
input terminal and OSC2 is normally open terminal.
INPUT
Maker Testing Terminal with Pull-down Resistance
The terminal is recommended to connect to GND.
