I/O
Port 1
is an 8-bit quasi-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. As inputs, port 1 pins being
externally pulled low will source current (
I
IL
, in the DC
characteristics) because of the internal pullup resistors.
Port 1 can also be switched into a bidirectional mode, in
which CMOS levels are provided. In this bidirectional
mode, each port 1 pin can be programmed individually
as input or output.
Port 1 also contains the interrupt, timer, clock, capture
and compare 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
(except when used for the compare functions).
The secondary functions are assigned to the pins of
port 1 as follows :
P1.0
INT3 CC0
Interrupt 3 input / compare 0 output /
capture 0 input
P1.1
INT4 CC1
Interrupt 4 input / compare 1 output /

P1.3
