8059D–AVR–11/09
• INT0/RXD1/PCINT26 – Port D, Bit 2
INT0, External Interrupt source 0. The PD2 pin can serve as an external interrupt source to the
MCU.
RXD1, RXD0, Receive Data (Data input pin for the USART1). When the USART1 receiver is
enabled this pin is configured as an input regardless of the value of DDD2. When the USART
forces this pin to be an input, the pull-up can still be controlled by the PORTD2 bit.
PCINT26, Pin Change Interrupt Source 26: The PD2 pin can serve as an external interrupt
source.
• TXD0/PCINT25 – Port D, Bit 1
TXD0, Transmit Data (Data output pin for the USART0). When the USART0 Transmitter is
enabled, this pin is configured as an output regardless of the value of DDD1.
PCINT25, Pin Change Interrupt Source 25: The PD1 pin can serve as an external interrupt
source.
• RXD0/T3/PCINT24 – Port D, Bit 0
RXD0, Receive Data (Data input pin for the USART0). When the USART0 receiver is enabled
this pin is configured as an input regardless of the value of DDD0. When the USART forces this
pin to be an input, the pull-up can still be controlled by the PORTD0 bit.
T3, Timer/Counter3 counter source.
PCINT24, Pin Change Interrupt Source 24: The PD0 pin can serve as an external interrupt
source.
