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 compati-
bility mode, and should not be used for 100% backward compatibility.
