Function
Port 1
is a bidirectional I/O port with internal
pull-up resistors. Port 1 pins that have
1 s written to them are pulled high by
the internal pull-up resistors, and in that
state can be used as inputs. As inputs,
port 1 pins being externally pulled low
will source current (I
characteristics) because of the internal
pull-up resistors. It is used for the low
order address byte during program
verifi-cation. It also contains the
interrupt, timer, clock, capture and
compare pins that are used by various
options. The output latch must be
programmed to a one (1) for that
function to operate (except when used
for the compare functions).
The secondary functions are assigned
to the port 1 pins as follows:
– INT3/CC0 (P1.0): interrupt 3 input/
– INT4/CC1 (P1.1): interrupt 4 input /
– INT5/CC2 (P1.2): interrupt 5 input /
– INT6/CC3 (P1.3): interrupt 6 input /
– INT2/CC4 (P1.4): interrupt 2 input /
– T2EX (P1.5): timer 2 external reload
– CLKOUT (P1.6): system clock
– T2 (P1.7): counter 2 input
