8.9
The port D is an 8-bit I/O port also functioning as data bus (D15 to D8) I/O pins. The port D has
the following registers.
• Port D data direction register (PDDDR)
• Port D data register (PDDR)
• Port D register (PORTD)
• Port D pull-up MOS control register (PDPCR)
8.9.1
PDDDR specifies input or output for the pins of the port D.
Since PDDDR is a write-only register, the bit manipulation instructions must not be used to write
PDDDR. For details, see section 2.9.4, Accessing Registers Containing Write-Only Bits.

Description
Modes 4 to 6:
Port D pins automatically function as data input/output
pins.
Mode 7:
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.
