DESCRIPTION
1 to 4
59 to 62 4 input channels to the ADC.
5

Port 4: 8-bit bidirectional I/O port. (P4.0 to P4.7). Port pins that have
logic 1s written to them are pulled HIGH by internal pull-ups, and in this
state can be used as inputs. As inputs, Port 4 pins that are externally
pulled LOW will source current (IIL, see Chapter 23) due to the internal
pull-ups. Port 4 output buffers can sink/source 4 LS TTL loads.
15
11
Reset: a HIGH level on this pin for two machine cycles while the
oscillator is running resets the device.
16
12
• Port 1: 8-bit bidirectional I/O port (P1.0 to P1.7). Same characteristics
17
13
as Port 4, but note that P1.6 and P1.7 are open-drain only.
18
14
• Alternative functions:
19
15
– INT2 to INT8 are external interrupt inputs
20
16
– STADC is the external trigger of the analog-to-digital converter
21
19
– T2 and T2EX are the Timer/event counter 2 inputs
22
20
– SCL and SDA are the I2C-bus clock and data lines.
23
21
24
22
Pulse Width Modulation output 0.
25
23
Enable Watchdog Timer: enable for Watchdog Timer and enable
Power-down mode.
26
24
Crystal oscillator output: output of the inverting amplifier of the
oscillator. Left open when external clock is used.
27
25
Crystal oscillator input: input to the inverting amplifier of the oscillator,
also the input for an externally generated clock source.
28
26
Ground: circuit ground potential.

• Port 3: 8-bit bidirectional I/O port (P3.0 to P3.7).
30
28
Same characteristics as Port 4
31

• Alternative functions:
32
30
– RXD is the UART serial data input (asynchronous) or data
33
31
input/output (synchronous)
34
32
– TXD is the UART serial data output (asynchronous) or clock output
(synchronous)
35
33
– INT0 and INT1 are external interrupts 0 and 1
36
34
– T0 and T1 are external inputs for timers 0 and 1.
