Alternate Functions of Port J
2570A–AVR–09/04
Port J is only present in ATmega3250/6450. The alternate pin configuration is as
follows:
Table 42. Port J Pins Alternate Functions
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 inter-
rupt source.
• PCINT29 – Port J, Bit 5
PCINT29, Pin Change Interrupt Source 29: The PE29 pin can serve as an external inter-
rupt source.
• PCINT28 – Port J, Bit 4
PCINT28, Pin Change Interrupt Source 28: The PE28 pin can serve as an external inter-
rupt source.
• PCINT27 – Port J, Bit 3
PCINT27, Pin Change Interrupt Source 27: The PE27 pin can serve as an external inter-
rupt source.
• PCINT26 – Port J, Bit 2
PCINT26, Pin Change Interrupt Source 26: The PE26 pin can serve as an external inter-
rupt source.
• PCINT25 – Port J, Bit 1
PCINT25, Pin Change Interrupt Source 25: The PE25 pin can serve as an external inter-
rupt source.
• PCINT24 – Port J, Bit 0
PCINT24, Pin Change Interrupt Source 24: The PE24 pin can serve as an external inter-
rupt source.
