Alternate Functions of Port C
The Port C alternate function is as follows:
Table 12-6.
The alternate pin configuration is as follows:
• ICP1/INT4/CLK0, Bit 7
ICP1, Input Capture pin 1 :The PC7 pin can act as an input capture for Timer/Counter1.
INT4, External Interrupt source 4 : The PC7 pin can serve as an external interrupt source to the
MCU.
CLK0, Clock Output : The PC7 pin can serve as oscillator clock ouput if the feature is enabled by
fuse.
• PCINT8/OC1A, Bit 6
PCINT8, Pin Change Interrupt source 8 : The PC6 pin can serve as an external interrupt source.
OC1A, Output Compare Match A output: The PC6 pin can serve as an external output for the
Timer/Counter1 Output Compare. The pin has to be configured as an output (DDC6 set “one”) to
serve this function. The OC1A pin is also the output pin for the PWM mode timer function.
• PCINT9/OC1B, Bit 5
PCINT9, Pin Change Interrupt source 9: The PC5 pin can serve as an external interrupt source.
OC1B, Output Compare Match B output: The PC5 pin can serve as an external output for the
Timer/Counter1 Output Compare. The pin has to be configured as an output (DDC5 set “one”) to
serve this function. The OC1B pin is also the output pin for the PWM mode timer function.
• PCINT10, Bit 4
PCINT10, Pin Change Interrupt source 10 : The PC4 pin can serve as an external interrupt
source.
• PCINT11, Bit 2
PCINT11, Pin Change Interrupt source 11 : The PC2 pin can serve as an external interrupt
source.
• Reset/dW, Bit 1
