Section 9 I/O Ports
9.7
Port D is an 8-bit I/O port that also has other functions. Port D has the following registers. For
details on register addresses and register states during each processing, refer to appendix A, On-
Chip I/O Register.
• Port D data direction register (PDDDR)
• Port D data register (PDDR)
• Port D register (PORTD)
• Port D pull-up MOS control register (PDPCR)
9.7.1
PDDDR is an 8-bit write-only register, the individual bits of which specify whether the pins of
port D are used for input or output.
PDDDR cannot be read; if it is, an undefined value will be read.

Description
When a pin is specified as a general purpose I/O
port, setting this bit to 1 makes the corresponding
port 1 pin an output pin. Clearing this bit to 0 makes
the pin an input pin.
