5. PIN FUNCTION
V
DD
: Supply voltage.
V
SS
: Circuit ground.
TEST
: Used for shipping inspection of the IC. For normal
operation, it should be connected to V
DD
.
RESET
: Reset the MCU.
X
IN
: Input to the inverting oscillator amplifier and input to
the internal main clock operating circuit.
X
OUT
: Output from the inverting oscillator 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~R24
: R2 is an 8-bit CMOS bidirectional I/O port. R2
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs .
