I/O
Port 1
is a bidirectional I/O port with internal pull-up resistors.
Port 1 pins that have 1s 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 also
contains the timer 2 and SSC pins as secondary function.
In general the output latch corresponding to a secondary
function must be programmed to a one (1) for that
function to operate.
For the outputs of the SSC (SCLK, STO) special circuitry
is implemented, providing true push-pull capability. The
STO output in addition will have true tristate capability.
When used for SSC inputs, the pull-up resistors will be
switched off and the inputs will float (high ohmic inputs).
The alternate functions are assigned to port 1, as follows:
