5. PIN FUNCTION

VDD: Supply voltage.

VSS: Circuit ground.

TEST: Used for shipping inspection of the IC. For normal

operation, it should not be connected .

RESET: Reset the MCU.

XIN: Input to the inverting oscillator amplifier and input to

the internal main clock operating circuit.

XOUT: Output from the inverting oscillator amplifier.

R00~R07: R0 is an 8-bit bidirectional I/O port. R0 pins 1

or 0 written to the Port Direction Register can be used as

outputs or inputs.

R10~R14: R1 is a 5-bit read only port. R1 pins 1 or 0 writ-

ten to the Port Direction Register can be used as inputs.

In addition, R1 serves the functions of the various follow-

ing special features.
