8.10.4 Pin Functions
Port C functions as IIC_2 and IIC_3 input/output, and PWMX output. The relationship between
register setting values and pin functions are as follows.
• PC7/PWX3
The pin function is switched as shown below according to the combination of the OEB bit in
DACR of the 14-bit PWMX and the PC7DDR bit.
OEB 0 1
PC7DDR 0 1 x
Pin function PC7 input pin PC7 output pin PWX3 output pin

• PC6/PWX2
The pin function is switched as shown below according to the combination of the OEA bit in
DACR of the 14-bit PWMX and the PC6DDR bit.
OEA 0 1
PC6DDR 0 1 x
Pin function PC6 input pin PC6 output pin PWX2 output pin

• PC3/SDA3
The pin function is switched as shown below according to the combination of the ICE bit in
ICCR of the IIC_3 and the PC3DDR bit.
ICE 0 1
PC3DDR 0 1 x
Pin function PC3 input pin PC3 output pin SDA3 input/output pin
