Atmel ATtiny24/44/84 [Preliminary]
• Port A, Bit 6 – ADC6/DI/SDA/OC1A/PCINT6
ADC6: Analog to Digital Converter, Channel 6
SDA: Two-wire mode Serial Interface Data.
DI: Data Input in USI Three-wire mode. USI Three-wire mode does not override normal port
functions, so pin must be configure as an input for DI function.
OC1A: Output compare match output: The PA6 pin can serve as an external output for the
Timer/Counter1 compare match A. The PA6 pin has to be configured as an output (DDA6 set
(one)) to serve this function. The OC1A pin 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 – ADC7/OC0B/ICP1/PCINT7
ADC7: Analog to Digital Converter, Channel 7
OC1B: Output compare match output: The PA7 pin can serve as an external output for the
Timer/Counter1 compare match B. The PA7 pin has to be configured as an output (DDA7 set
(one)) to serve this function. The OC1B pin is also the output pin for the PWM mode timer
function.
ICP1: Input capture pin: The PA7 pin can act as an input capture pin for Timer/Counter1.
PCINT7: Pin change interrupt source 7. The PA7 pin can serve as an external interrupt source
for pin change interrupt 0.
