Function

Power supply pin

Connect all VDD pins to the power supply.

GND pin

Connect all GND pins to GND.

Analog reference voltage pin

Analog GND pin

Sub clock oscillation input pin

Connect to a crystal oscillator of f = 32.768 kHz.

Sub clock oscillation output pin

Connect to a crystal oscillator of f = 32.768 kHz.

The clock output is opposite in phase to XT0.

Main clock oscillation input pin

Connect to a crystal or ceramic oscillator. Or, input an external

clock.

Main clock oscillation output pin

Connect to a crystal or ceramic oscillator.

The clock output is opposite in phase to OSC0.

Leave this pin unconnected when an external clock is used.

Reset input pin

Non-maskable interrupt input pin

External program memory access input pin

If the EA pin is enabled (low level), the internal program memory is

masked and the CPU executes the program code in external

program memory through all address space.
