2543A–AVR–08/03

PCINT6: Pin Change Interrupt Source 6. The PB6 pin can serve as an external interrupt

source.

• DI/SDA/PCINT5 - Port B, Bit 5

DI: Three-wire mode Universal Serial Interface Data input. Three-wire mode does not

override normal port functions, so pin must be configured as an input. SDA: Two-wire

mode Serial Interface Data.

PCINT5: Pin Change Interrupt Source 5. The PB5 pin can serve as an external interrupt

source.

• OC1B/PCINT4 – Port B, Bit 4

OC1B: Output Compare Match B output: The PB4 pin can serve as an external output

for the Timer/Counter1 Output Compare B. The pin has to be configured as an output

(DDB6 set (one)) to serve this function. The OC1B pin is also the output pin for the PWM

mode timer function.

PCINT4: Pin Change Interrupt Source 4. The PB4 pin can serve as an external interrupt

source.

• OC1A/PCINT3 – Port B, Bit 3

OC1A: Output Compare Match A output: The PB3 pin can serve as an external output

for the Timer/Counter1 Output Compare A. The pin has to be configured as an output

(DDB3 set (one)) to serve this function. The OC1A pin is also the output pin for the PWM

mode timer function.

PCINT3: Pin Change Interrupt Source 3: The PB3 pin can serve as an external interrupt

source.

• OC0A/PCINT2 – Port B, Bit 2

OC0A: Output Compare Match A output. The PB2 pin can serve as an external output

for the Timer/Counter0 Output Compare A. The pin has to be configured as an output

(DDB2 set (one)) to serve this function. The OC1A pin is also the output pin for the PWM

mode timer function.

PCINT2: Pin Change Interrupt Source 2. The PB2 pin can serve as an external interrupt

source.
