Note :
Port Pi (i = 0 to 3) has the port Pi direction register which can be used to program each bit as an input (“0”) or an output (“1”). The pins programmed as “1” in
the direction register are output pins. When pins are programmed as “0,” they are input pins. When pins are programmed as output pins, the output data are
written into the port latch and then output. When data is read from the output pins, the output pin level is not read but the data of the port latch is read. This
allows a previously-output value to be read correctly even if the output “L” voltage has risen, for example, because a light emitting diode was directly driven.
The input pins are in the floating state, so the values of the pins can be read. When data is written into the input pin, it is written only into the port latch, while
the pin remains in the floating state.
