Alternate Functions of Port B
The Port B pins with alternate function are shown in
Table 10-3.
• Port B, Bit 0 – ADC0/AIN0/OC0A/PCINT0/TPIDATA
• Port B, Bit 1 – ADC1/AIN1/CLKI/ICP0/OC0B/PCINT1/TPICLK
• ADC0: Analog to Digital Converter, Channel 0
• AIN0: Analog Comparator Positive Input. Configure the port pin as input with the internal pull-

Timer/Counter0 Compare Match A. The pin has to be configured as an output (DDB0 set
(one)) to serve this function. This is also the output pin for the PWM mode timer function.
