In all modes, port D bits [5:0] can be used either for general-purpose I/O
or with the serial communications interface (SCI) and serial peripheral
interface (SPI) subsystems. During reset, port D pins PD[5:0] are
configured as high-impedance inputs (DDRD bits cleared).

When DDRD bit 5 is 1 and MSTR = 1 in SPCR, PD5/SS is a
general-purpose output and mode fault logic is disabled.
0 = Input
1 = Output
I = Indeterminate after reset
