Alternate Functions of Port B

The Port B pins with alternate function are shown in Table 10-3 on page 48.

• 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.
