Writes do not change pin state when pin is configured for PWM outputs,
only after the PWM channel becomes available on port P pin, see PWEN
bit description.
This register determines whether each pin is input or output when it is
selected to be a general purpose I/O pin. Reading Port P Data Register
always follows pin data associated with he Port P Data Direction bit.
Read and write any time.
DDRP[7:0] — Data Direction Port P pins
DDP6
PWM functions share port P pins 3 to 0 and take precedence over the
general-purpose port when enabled.
READ: any time (input configured pin return pin level; output
configured pin return internal latch pin driver input level.
WRITE: Data stored in an internal latch (drives pins only if configured
for output and corresponding PWM channel not enabled).
