Port 5: Port 5 is an 8-bit I/O port with a user-congurable
output type. During reset Port 5 latches are congured in the
input only mode with the internal pull-up disabled. The
operation of Port 5 pins as inputs and outputs depends upon
the port conguration selected. Each port pin is congured
All pins have Schmitt triggered inputs.
Port 5 also provides various special functions as described
