9.11
Port D is an 8-bit I/O port and 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)
9.11.1
PDDDR specifies input or output the port D pins using the individual bits. PDDDR cannot be
read; if it is, the read value is undefined. Since this register is a write-only register, bit-
manipulation instructions should not be used when writing. See section 2.9.4, Access Method for
Registers with Write-only Bits.

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