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.
Port pin
Alternate function
R10 AD0 (A/D converter input 0)
R11 AD1 (A/D converter input 1)
R12 AD2 (A/D converter input 2)

R14 AD4 (A/D converter input 4)
R20~R25: R2 is a 6-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.
Port pin

R30~R37: R3 is 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.
In addition, R3 serves the functions of the various follow-
ing special features.

with 14bit resolution
R36 BUZ (Buzzer output)
R37 TMR1 (Timer Interrupt 1)
R40~R43: R4 is a 4-bit open drain I/O port. Each pins 1 or
0 written to the their Port Direction Register can be used as
outputs or inputs.
In addition, R4 serves the functions of the various follow-
ing special features.
Port pin
Alternate function
R40 SCL0 (I2C Clock 0)
R41 SDA0 (I2C Data0)
R42 SCL1 (I2C Clock 1)
R43 SDA1 (I2C Data 1)
