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
