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 *
Note: * Modes 6 and 7 are not available in the ROMless versions.

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 PDDDR bits to 1 makes the corresponding port D pins output ports, while clearing the
bits to 0 makes the pins input ports.
