Section 28 I/O Port
28.4 Port C
Port C is an input/output port with the pin configuration shown in figure 28.3. Each pin has an
input pull-up/pull-down MOS, which is controlled by the port C control register (PCCR) in the
PFC. Select pull-up or pull-down MOS with PINT control register A (PINTCRA) in the PFC.

28.4.1 Port C Data Register (PCDR)
PCDR is a register that stores data for pins PTC7 to PTC0. Bits PC7DT to PC0DT correspond to
pins PTC7 to PTC0. For pins that function as general-purpose output pins, a read operation
directly reads out the corresponding value from this register. For pins that function as general-
purpose input pins, a read operation reads out the level on the corresponding pin.
