Power Source ( 0V )

INPUT

Internal Oscillator Terminals.

OUTPUT

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.

INPUT

2-bit Input PORTF.

INPUT

Selects a function of either of 1) or 2) for PORTF by the

mask option.

1) External Interrupt Input Terminal with Pull up

resistance :EXTI ( IIP,II )
