In ATmega103 compatibility mode, DDRC and PINC Registers are initialized to being Push-pull
Zero Output. The port pins assumes their Initial Value, even if the clock is not running. Note that
the DDRC and PINC registers are available in ATmega103 compatibility mode, and should not
be used for 100% backward compatibility.
