Port 1: Port 1 is an 8-bit I/O port with a user-congurable
output type, except for three pins as noted below. During
reset Port 1 latches are congured in the input only mode
with the internal pull-up disabled. The operation of the
congurable Port 1 pins as inputs and outputs depends upon
the port conguration selected. Each of the congurable port
pins are programmed independently. Refer to Section 7.13.1
details. P1.2 to P1.3 are open drain when used as outputs.
P1.5 is input only.
All pins have Schmitt triggered inputs.
Port 1 also provides various special functions as described
below:
