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-
• OC0A, Output Compare Match output: The PB0 pin can serve as an external output for the
• PCINT0: Pin Change Interrupt source 0. The PB0 pin can serve as an external interrupt
• TPIDATA: Serial Programming Data.
• ADC1: Analog to Digital Converter, Channel 1
• AIN1: Analog Comparator Negative Input. Configure the port pin as input with the internal
• CLKI: External Clock.
• ICP0: Input Capture Pin. The PB1 pin can act as an Input Capture pin for Timer/Counter0.
