Alternate Functions of Port B
The Port B pins with alternate functions are shown in Table 13-6.
The alternate pin configuration is as follows:
OC2A/PCINT15, Bit 7
OC2, Output Compare Match A output: The PB7 pin can serve as an external output for the
Timer/Counter2 Output Compare A. The pin has to be configured as an output (DDB7 set (one))
to serve this function. The OC2A pin is also the output pin for the PWM mode timer function.
