8197A–AVR–10/09

ATtiny261A/461A/861A

• ADC10: ADC input Channel 10. Note that ADC input channel 10 uses analog power.

• PCINT15: Pin Change Interrupt source 15.

• Port B, Bit 6 - ADC9/ T0/ INT0/ PCINT14

• ADC9: ADC input Channel 9. Note that ADC input channel 9 uses analog power.

• T0: Timer/Counter0 counter source.

• INT0: The PB6 pin can serve as an External Interrupt source 0.

• PCINT14: Pin Change Interrupt source 14.

• Port B, Bit 5 - XTAL2/ CLKO/ ADC8/ PCINT13

• XTAL2: Chip clock Oscillator pin 2. Used as clock pin for crystal Oscillator or Low-frequency

crystal Oscillator. When used as a clock pin, the pin can not be used as an I/O pin.

• CLKO: The divided system clock can be output on the PB5 pin, if the CKOUT Fuse is

programmed, regardless of the PORTB5 and DDB5 settings. It will also be output during

reset.

• OC1D Output Compare Match output: The PB5 pin can serve as an external output for the

Timer/Counter1 Compare Match D when configured as an output (DDA1 set). The OC1D pin

is also the output pin for the PWM mode timer function.

• ADC8: ADC input Channel 8. Note that ADC input channel 8 uses analog power.

• PCINT13: Pin Change Interrupt source 13.

• Port B, Bit 4 - XTAL1/ CLKI/ OC1B/ ADC7/ PCINT12

• XTAL1/CLKI: Chip clock Oscillator pin 1. Used for all chip clock sources except internal

calibrated oscillator. When used as a clock pin, the pin can not be used as an I/O pin.

•OC1D: Inverted Output Compare Match output: The PB4 pin can serve as an external output

for the Timer/Counter1 Compare Match D when configured as an output (DDA0 set). The

OC1D pin is also the inverted output pin for the PWM mode timer function.

• ADC7: ADC input Channel 7. Note that ADC input channel 7 uses analog power.

• PCINT12: Pin Change Interrupt source 12.

• Port B, Bit 3 - OC1B/ PCINT11

• OC1B, Output Compare Match output: The PB3 pin can serve as an external output for the

Timer/Counter1 Compare Match B. The PB3 pin has to be configured as an output (DDB3

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

function.

• PCINT11: Pin Change Interrupt source 11.

• Port B, Bit 2 - SCK/ USCK/ SCL/ OC1B/ PCINT10

• USCK: Three-wire mode Universal Serial Interface Clock.

• SCL: Two-wire mode Serial Clock for USI Two-wire mode.

•OC1B: Inverted Output Compare Match output: The PB2 pin can serve as an external output

for the Timer/Counter1 Compare Match B when configured as an output (DDB2 set). The

OC1B pin is also the inverted output pin for the PWM mode timer function.

• PCINT10: Pin Change Interrupt source 10.

• Port B, Bit 1 - MISO/ DO/ OC1A/ PCINT9
