Notes : Port Pi (i = 0 to 3) has a port Pi direction register that can be used to program each bit for 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 is
written into the port latch and then output. When data is read from the output pins, the data of the port latch, not the output pin level, is read. This allows a
previously output value to be read correctly even if the output LOW voltage has risen due to, for example, a directly-driven light emitting diode. The input pins
are in the floating state, so the values of the pins can be read. When data is written to the input pin, it is written only into the port latch, while the pin remains
in the floating state.
