Alternate Functions of Port J

Port J is only present in ATmega3250P. 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.
