Description
Power
Supply
VDD
—
+5V digital power supply (common to analog power supply)
GND
—
0V digital ground (common to analog ground)
OSC0
I
Oscillator input pin: connects to a crystal oscillator (or ceramic resonator)
or external clock. The master clock and external clock are used as the
system clock without frequency division.
OSC1
O
Oscillator input pin: connects to a crystal oscillator (or ceramic resonator).
When an external clock is input to OSC0, leave OSC1 open.
RESET
I
System reset input: when this pin goes low, the internal state of the chip
is initialized and program execution restarts from address 0040H. The
input is pulled up to VDD with an internal pull-up resistor.
Oscillation
TEST
I
Test input pin: connects to ground pin.

P0.7
I/O
8-bit input/output port (Port 0)
I/O
8-bit input/output port (Port 1)
I/O
8-bit input/output port (Port 2): input or output can be selected for each
bit by the port 2 direction register (P2DIR). In addition to their input/
output port functions, the pins of port 2 have secondary functions: see
the next table.
I/O
8-bit input/output port (Port 3): input or output can be selected for each
bit by the port 3 direction register (P3DIR). In addition to their input/
output port functions, the pins of port 3 have secondary functions: see
the next table.
I
8-bit input port (Port 6):
Functions as analog input channel during A/D conversion.
