output or input of a peripheral module.
2.4.2
Registers
lists the implemented configuration bits which are available on each port. These registers
except the pin input registers can be written at any time, however a specific configuration might not
become active. For example a pull-up device does not become active while the port is used as a push-pull
output.
Unimplemented bits read zero.
2.4.3
Pin I/O Control
illustrates the data paths to and from an I/O pin. Input and output data can always be read via
Section 2.3.3.2, “Port Input Register
”) independent of if the pin is used as
general-purpose I/O or with a shared peripheral function. If the pin is configured as input (DDRx=0,
Section 2.3.3.3, “Data Direction Register
”), the pin state can also be read through the data register (PTx,
Section 2.3.3.1, “Port Data Register
”).
