Alternate Functions of Port B
The Port B pins with alternate function are shown in
Table 10-7.
• Port B, Bit 0 – XTAL1/PCINT8
• Port B, Bit 1 – XTAL2/PCINT9
• Port B, Bit 2 – INT0/OC0A/CKOUT/PCINT10
• XTAL1: Chip Clock Oscillator pin 1. Used for all chip clock sources except internal
• PCINT8: Pin Change Interrupt source 8. The PB0 pin can serve as an external interrupt
• CLKI: Clock Input from an external clock source, see
• XTAL2: Chip Clock Oscillator pin 2. Used as clock pin for all chip clock sources except
• PCINT9: Pin Change Interrupt source 9. The PB1 pin can serve as an external interrupt
• INT0: External Interrupt Request 0.
• OC0A: Output Compare Match output: The PB2 pin can serve as an external output for the
• CKOUT - System Clock Output: The system clock can be output on the PB2 pin. The system
• PCINT10: Pin Change Interrupt source 10. The PB2 pin can serve as an external interrupt
calibrateble RC oscillator. When used as a clock pin, the pin can not be used as an I/O pin.
When using internal calibratable RC Oscillator as a chip clock source, PB0 serves as an
ordinary I/O pin.

Timer/Counter0 Compare Match A. The PB2 pin has to be configured as an output (DDB2
set (one)) to serve this function. The OC0A pin is also the output pin for the PWM mode timer
function.
