V
DD
: Supply voltage.
V
SS
: Circuit ground.
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.
RA0~RA7
: RA is an 8-bit, CMOS, bidirectional I/O port.
RA pins can be used as outputs or inputs according to “1”
or “0” written the their Port Direction Register(RAIO).
In addition, RA serves the functions of the various special
features in Table 5-1 .
RB0~RB7
: RB is a 8-bit, CMOS, bidirectional I/O port.
RB pins can be used as outputs or inputs according to “1”
or “0” written the their Port Direction Register(RBIO).
RB serves the functions of the various following special
features
in
Table 5-2
RC3~RC6
: RC is a 4-bit, CMOS, bidirectional I/O port.
RC pins can be used as outputs or inputs according to “1”
or “0” written the their Port Direction Register(RCIO).
RC serves the functions of the serial interface following
special features in Table 5-3 .
RD0~RD2
: RD is a 3-bit, CMOS, bidirectional I/O port.
RC pins can be used as outputs or inputs according to “1”
or “0” written the their Port Direction Register(RDIO).
RD serves the functions of the external interrupt following
special features in Table 5-4
