I/O
Port 3
is an 8-bit quasi-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. As inputs,
port 3 pins being externally pulled low will source
current (I IL, in the DC characteristics) because of the
internal pullup resistors. Port 3 also contains the
interrupt, timer, serial port and external memory
strobe pins that are used by various options. 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:
P3.0 / RxD
Receiver data input (asynch.) or
data
input/output (synch.) of serial
interface
P3.1 / TxD
Transmitter data output (asynch.) or
clock output (synch.) of serial
interface
P3.2 / INT0
External interrupt 0 input /
timer 0 gate control input
P3.3 / INT1
External interrupt 1 input /
timer 1 gate control input
P3.4 / T0
Timer 0 counter input
P3.5 / T1
Timer 1 counter input
P3.6 / WR
WR control output; latches the data
byte
from port 0 into the external data
memory
P3.7 / RD
RD control output; enables the
external data memory
