ATmega640/1280/1281/2560/2561
• TXD3/PCINT10 - Port J, Bit 1
TXD3, USART3 Transmit pin.
PCINT10, Pin Change Interrupt Source 10. The PJ1 pin can serve as External Interrupt
Sources.
• RXD3/PCINT9 - Port J, Bit 0
RXD3, USART3 Receive pin. Receive Data (Data input pin for the USART3). When the
USART3 Receiver is enabled, this pin is configured as an input regardless of the value of DDJ0.
When the USART3 forces this pin to be an input, a logical one in PORTJ0 will turn on the inter-
nal pull-up.
PCINT9, Pin Change Interrupt Source 9. The PJ0 pin can serve as External Interrupt Sources.
