pin.
Function
Connect it to the V
SS
pin.
A “L” on this input resets the microcomputer.
These pins are provided for the main clock generating circuit.
Connect a ceramic resonator or crystal between the X
IN
and the
X
OUT
pins. To use an externally derived clock, input it to the
X
IN
pin and leave the X
OUT
pin open.
This pin is a power supply input for the A-D converter. Connect
it to V
CC
.
This pin is a power supply input for the A-D converter. Connect
it to V
SS
.
This pin is a reference voltage input for the A-D converter.
This is an 8-bit CMOS I/O port. It has an input/output port
direction register that allows the user to set each pin for input or
output individually. When set for input, the user can specify in
units of four bits via software whether or not they are tied to a
pull-up resistor.
This is an 8-bit I/O port equivalent to P0.
This is a 6-bit I/O port equivalent to P0.
This is a 6-bit I/O port equivalent to P0. The P4
0
pin is shared
with timer A0 input and serial I/O output TxD1. The P4
1
pin is
shared with timer A0 output. The P4
2
pin is shared with serial
I/O input RxD1. The P4
3
pin is shared with external interrupt
INT0 and timer X0 input/output TX0
INOUT
. The P4
4
pin is
shared with external interrupt INT1 and timer X1 input/output
TX1
INOUT
. The P4
5
pin is shared with timer X2 input/output
TX2
INOUT
.

.
This is an 8-bit I/O port equivalent to P0. These pins are shared
with analog input pins AN
0
through AN

.
This is a 2-bit I/O port equivalent to P0 . These pins are used
for input/output to and from the oscillator circuit for the clock.
Connect a crystal oscillator between the X
CIN
and the X
COUT
pins.
