ATtiny43U
PCINT10: Pin Change Interrupt source 10. The PB2 pin can serve as an external interrupt
source for pin change interrupt 1.
Port B, Bit 3 – T1/CLKO/PCINT11
T1: Timer/Counter1 Counter source.
CLKO: System Clock Output. The system clock can be output on the PB3 pin. The system clock
will be output if the CKOUT Fuse is programmed, regardless of the PORTB3 and DDB3 settings.
It will also be output during reset.
PCINT11: Pin Change Interrupt source 11. The PB3 pin can serve as an external interrupt
source for pin change interrupt 1.
Port B, Bit 4 – DI/SDA/OC1A/PCINT12
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.
SDA: Two-wire mode Serial Interface Data.
OC1A, Output Compare Match output: The PB4 pin can serve as an external output for the
Timer/Counter1 Compare Match A. The PB4 pin has to be configured as an output (DDB4 set
(one)) to serve this function. The OC1A pin is also the output pin for the PWM mode timer
function.
PCINT12: Pin Change Interrupt source 12. The PB4 pin can serve as an external interrupt
source for pin change interrupt 1.
Port B, Bit 5 – DO/OC1B/PCINT13
DO: Data Output in USI Three-wire mode. Data output (DO) overrides PORTB5 value and it is
driven to the port when the data direction bit DDB5 is set (one). However the PORTB5 bit still
controls the pullup, enabling pullup if direction is input and PORTB5 is set (one).
OC1B: Output Compare Match output: The PB5 pin can serve as an external output for the
Timer/Counter1 Compare Match B. The PB5 pin has to be configured as an output (DDB5 set
(one)) to serve this function. The OC1B pin is also the output pin for the PWM mode timer
function.
PCINT13: Pin Change Interrupt source 13. The PB5 pin can serve as an external interrupt
source for pin change interrupt 1.
Port B, Bit 6 – USCK/SCL/PCINT14
USCK: Three-wire mode Universal Serial Interface Clock.
SCL: Two-wire mode Serial Clock for USI Two-wire mode.
PCINT14: Pin Change Interrupt source 14. The PB6 pin can serve as an external interrupt
source for pin change interrupt 1.
Port B, Bit 7 – INT0/PCINT15
INT0: External Interrupt Request 0.
PCINT15: Pin Change Interrupt source 15. The PB7 pin can serve as an external interrupt
source for pin change interrupt 1.
