Note:
Port C Data Direction Register (PCDDR)
PCDDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port C. PCDDR cannot be read; if it is, an undefined value will be read.
PCDDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode. As the SCI is initialized, pin states are determined by the PCDDR and
PCDR specifications. The OPE bit in SBYCR is used to select whether the address output pins
retain their output state or become high-impedance when a transition is made to software standby
mode.

Initial value :
R/W
Modes 4 and 5
The corresponding port C pins are address outputs irrespective of the value of the PCDDR bits.
Mode 6
Setting a PCDDR bit to 1 makes the corresponding port C pin an address output, while
clearing the bit to 0 makes the pin an input port.
Mode 7
Setting a PCDDR bit to 1 makes the corresponding port C pin an output port, while clearing
the bit to 0 makes the pin an input port.
