7.13
Port C is an 8-bit I/O port. Port C pins also function as IIC3_2 and IIC3_3 I/O pins and on-chip
emulator I/O pins. The output format for PC0 to PC3 which are general I/O ports is NMOS push-
pull output. PC4 to PC7 which are general input ports are not supported by the on-chip emulator.
Port C has the following registers.
• Port C data direction register (PCDDR)
• Port C data register (PCDR)
• Port C register (PORTC)
7.13.1
The individual bits in PCDDR specify input or output for the pins of port C. The read value is
undefined.
7.13.2
PCDR stores output data for the port C pins.

Description
Reserved
These bits cannot be modified.
While a general I/O port function is selected, the
corresponding port C pin is an output port when a
PCDDR bit is set to 1, and an input port when
cleared to 0.
Description
Reserved
The initial value should not be changed.
PCDR stores output data for the port C pins that
are used as the general output ports.
