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.
The port is used for the low-order address byte during
program verification. 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
port 1 pins 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 /
capture 1 input
