7.12
Port C and port D are two sets of 8-bit I/O ports. Port C and port D have the following registers.
• Port C data direction register (PCDDR)
• Port C output data register (PCODR)
• Port C input data register (PCPIN)
• Port C Nch-OD control register (PCNOCR)
• Port D data direction register (PDDDR)
• Port D output data register (PDODR)
• Port D input data register (PDPIN)
• Port D Nch-OD control register (PDNOCR)
7.12.1
PCDDR and PDDDR select input or output for the pins of port C and port D on a bit-by-bit basis.
