ATTINY1634_14 Datasheet, PDF (62/259 Pages) ATMEL Corporation – 8-bit AVR Microcontroller with 16KB In-system

● Port A, Bit 3 – ADC0/T1/PCINT3
● ADC0: Analog to digital converter, channel 0.
● SNS: Sense line for capacitive measurement using QTouch technology. Connected to C_S.
● T1: Timer/Counter1 counter source.
● PCINT3: Pin change interrupt source 3. The PA3 pin can serve as an external interrupt source for pin change interrupt
0.
● Port A, Bit 4 – ADC1/T0/PCINT4
● ADC1: Analog to digital converter, channel 1.
● T0: Timer/Counter0 counter source.
● PCINT4: Pin change Interrupt source 4. The PA4 pin can serve as an external interrupt source for pin change interrupt
0.
● Port A, Bit 5 – ADC2/OC0B/PCINT5
● ADC2: Analog to digital converter, channel 2.
● OC0B: Output compare match output. The PA5 pin can serve as an external output for the Timer/Counter0 compare
match B. The PA5 pin has to be configured as an output (DDA5 set (“1”)) to serve this function. The OC0B pin is also
the output pin for the PWM mode timer function.
● PCINT5: Pin change interrupt source 5. The PA5 pin can serve as an external interrupt source for pin change interrupt
0.
● Port A, Bit 6 – ADC3/OC1B/PCINT6
● ADC3: Analog to digital converter, channel 3.
● OC1B: Output compare match output. The PA6 pin can serve as an external output for the Timer/Counter1 compare
match B. The pin has to be configured as an output (DDA6 set (“1”)) to serve this function. This is also the output pin
for the PWM mode timer function.
● PCINT6: Pin change interrupt source 6. The PA6 pin can serve as an external interrupt source for pin change interrupt
0.
● Port A, Bit 7 – ADC4/RXD0/PCINT7
● ADC4: Analog to digital converter, channel 4.
● RXD0: UART0 data receiver.
● PCINT7: Pin change interrupt source 7. The PA7 pin can serve as an external interrupt source for pin change interrupt
0.
