PCODR and PDODR are 8-bit read/write registers that store output data for the pins on ports C
and D (PC7 to PC0 and PD7 to PD0). PCODR and PDODR can always be read from or written to,
regardless of the PCDDR and PDDDR settings.
PCODR and PDODR are initialized to H'00 by a reset and in hardware standby mode. They retain
their prior states in software standby mode.
