11.1.1
DDR is an 8-bit write-only register that specifies the port input or output for each bit. A read from
the DDR is invalid and DDR is always read as an undefined value.
When the general I/O port function is selected, the corresponding pin functions as an output port
by setting the corresponding DDR bit to 1; the corresponding pin functions as an input port by
clearing the corresponding DDR bit to 0.
The initial DDR values are shown in table 11.3.

Note: The lower six bits are valid and the upper two bits are reserved for port 6 registers.
The lower five bits are valid and the upper three bits are reserved for port F registers.
