Section 11 I/O Ports
11.12
Port D is an 8-bit I/O port that also has other functions. 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)
• Port D open drain control register (PDODR)
11.12.1 Port D Data Direction Register (PDDDR)
The individual bits of PDDDR specify input or output for the pins of port D. PDDDR cannot be
read; if it is, an undefined value will be read.
