• Port B, Bit 0 – ADC0/AIN0/OC0A/PCINT0/TPIDATA
• ADC0: Analog to Digital Converter, Channel 0 (ATtiny5/10, only)
• AIN0: Analog Comparator Positive Input. Configure the port pin as input with the internal pull-up switched off to
avoid the digital port function from interfering with the function of the Analog Comparator.
• OC0A, Output Compare Match output: The PB0 pin can serve as an external output for the 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.
• PCINT0: Pin Change Interrupt source 0. The PB0 pin can serve as an external interrupt source for pin change
interrupt 0.
• TPIDATA: Serial Programming Data.
• Port B, Bit 1 – ADC1/AIN1/CLKI/ICP0/OC0B/PCINT1/TPICLK
• ADC1: Analog to Digital Converter, Channel 1 (ATtiny5/10, only)
• AIN1: Analog Comparator Negative Input. Configure the port pin as input with the internal pull-up switched off to
avoid the digital port function from interfering with the function of the Analog Comparator.
• CLKI: External Clock.
• ICP0: Input Capture Pin. The PB1 pin can act as an Input Capture pin for Timer/Counter0.
• OC0B: Output Compare Match output: The PB1 pin can serve as an external output for the Timer/Counter0
Compare Match B. The PB1 pin has to be configured as an output (DDB1 set (one)) to serve this function. The
OC0B pin is also the output pin for the PWM mode timer function.
