Alternate functions of Port J
Port J is only present in Atmel ATmega3250A/3250PA/6450A/6450P. The alternate pin configuration is as follows:
The alternate pin configuration is as follows:
PCINT30 – Port J, Bit 6
PCINT30, Pin Change Interrupt Source 30: The PE30 pin can serve as an external interrupt source.
PCINT29 – Port J, Bit 5
PCINT29, Pin Change Interrupt Source 29: The PE29 pin can serve as an external interrupt source.
PCINT28 – Port J, Bit 4
PCINT28, Pin Change Interrupt Source 28: The PE28 pin can serve as an external interrupt source.
PCINT27 – Port J, Bit 3
PCINT27, Pin Change Interrupt Source 27: The PE27 pin can serve as an external interrupt source.
