Function
Port 0 is an 8-bit open drain bidirectional I/O-port. Port 0
pins that have 1 s written to them float; in this state they
can be used as high-impedance inputs.
Port 1 is an 8-bit bidirectional I/O-port with internal pullup
resistors. Port 1 pins that have 1 s written to them are
pulled high by the internal pullup resistors, and in that state
can be used as inputs. These eight bits also contain the
output channels of the pulse width modulation unit. The
secondary functions are assigned to the pins of port 1 as
follows:
PWMi (P1.i): output of PWM-channel i (i = 0, …, 7).
Port 2 is a multifunction port with P2.0 – P2.3 working as
digital or analog inputs. Port bits P2.4 – P2.7 are
bidirectional I/O-lines with internal pullup resistors.
Port 3 is an 8-bit bidirectional I/O-port with internal pullup
resistors. Port 3 pins that have 1 s written to them are
pulled high by the internal pullup resistors, and in that state
can be used as inputs. It also contains the interrupt, timer
and serial port pins. The output latch corresponding to a
secondary function must be programmed to a one (1) for
that function to operate.
The secondary functions are assigned to the pins of port 3,
as follows:
– INT0 (P3.2)
– INT1 (P3.3)
– T0 (P3.4)
– T1 (P3.5)
– RxD (P3.6)
– TxD (P3.7)
: interrupt 0 input/timer 0 gate control input
: interrupt 1 input/timer 1 gate control input
: counter 0 input
: counter 1 input
: serial port receive line
: serial port transmit line.
