NOTE:
To avoid generating a glitch on an I/O port pin, data should be written to
the I/O port data register before writing a logic 1 to the corresponding
data direction register.
At power-on or reset, all DDRs are cleared, which configures all port pins
as inputs. The DDRs are capable of being written to or read by the
processor. During the programmed output state, a read of the data
register will actually read the value of the output data latch and not the
level on the I/O port pin.
