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.

OSC1: Input to the internal On Screen Display operating

circuit.

OSC2: Output from the inverting OSC1 amplifier.

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

pins 1 or 0 written to the Port Direction Register can be

used as outputs or inputs.

R10~R17: R1 is an 8-bit CMOS bidirectional I/O port. R1

pins 1 or 0 written to the Port Direction Register can be

used as outputs or inputs.

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

ing special features.

R20~R27: R2 is a 8-bit CMOS bidirectional I/O port. Each

pins 1 or 0 written to the their Port Direction Register can

be used as outputs or inputs.

In addition, R2 serves the functions of the various follow-

ing special features.

R40~R47: R40~R43 are 8-bit NMOS open drain output

and R45~R47 are bidirectional CMOS Input / NMOS open

drain output port. R4 pins 1 or 0 written to the Port Direc-

tion Register can be used as outputs or inputs.

In addition, R4 serves the functions of the various follow-

ing special features.

R50~R56: R50~R53 are 4-bit CMOS bidirectional I/O and

R54~R56 are CMOS output port. R5 pins 1 or 0 written to

the Port Direction Register can be used as outputs or in-

puts.

In addition, R5 serves the functions of the various follow-

ing special features.

R67: R67 is an 1-bit CMOS bidirectional I/O port. R67

pins 1 or 0 written to the Port Direction Register can be

used as outputs or inputs.

In addition, R67 serves the functions of the various follow-

ing special features.

R,G,B: R,G,B CMOS output port. Each pins controls Red,

Green,. Blue color control.
