Port D Data Direction Register (PDDDR)
PDDDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port D. PDDDR cannot be read; if it is, an undefined value will be read.
PDDDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
• Modes 4 to 6
• Mode 7

Bit
Initial value :
R/W
The input/output direction specification by PDDDR is ignored, and port D is automatically
designated for data I/O.
Setting a PDDDR bit to 1 makes the corresponding port D pin an output port, while clearing
the bit to 0 makes the pin an input port.
