Alternate Functions of Port B
The Port B pins with alternate function are shown in Table 11-8 on page 75.
Port B, Bit 0 – T0/PCINT8
T0: Timer/Counter0 Counter Source.
PCINT8: Pin Change Interrupt source 8. The PB0 pin can serve as an external interrupt source
for pin change interrupt 1.
Port B, Bit 1 – OC0A/PCINT9
OC0A: Output Compare Match output: The PB1 pin can serve as an external output for the
Timer/Counter0 Compare Match A. The PB1 pin has to be configured as an output (DDB1 set
(one)) to serve this function. The OC0A pin is also the output pin for the PWM mode timer
function.
PCINT9: Pin Change Interrupt source 9. The PB1 pin can serve as an external interrupt source
for pin change interrupt 1.
Port B, Bit 2 – OC0B/PCINT10
OC0B: Output Compare Match output: The PB2 pin can serve as an external output for the
Timer/Counter0 Compare Match A. The PB2 pin has to be configured as an output (DDB2 set
(one)) to serve this function. The OC0B pin is also the output pin for the PWM mode timer
function.
