Alternate Functions of Port D
The Port D pins with alternate functions are shown in Table 14-12.
The alternate pin configuration is as follows:
OC2A/PCINT31 – Port D, Bit 7
OC2A, Output Compare Match A output: The PD7 pin can serve as an external output for the
Timer/Counter2 Output Compare A. The pin has to be configured as an output (DDD7 set (one))
to serve this function. The OC2A pin is also the output pin for the PWM mode timer function.
PCINT31, Pin Change Interrupt Source 31:The PD7 pin can serve as an external interrupt
source.
ICP1/OC2B/PCINT30 – Port D, Bit 6
ICP1, Input Capture Pin 1: The PD6 pin can act as an input capture pin for Timer/Counter1.
OC2B, Output Compare Match B output: The PD6 pin can serve as an external output for the
Timer/Counter2 Output Compare B. The pin has to be configured as an output (DDD6 set (one))
to serve this function. The OC2B pin is also the output pin for the PWM mode timer function.
PCINT30, Pin Change Interrupt Source 30: The PD6 pin can serve as an external interrupt
source.
