Alternate Functions of Port J
Table 13-18. Overriding Signals for Alternate Functions in PH3:0
Port J is only present in ATmega3250/6450. The alternate pin configuration is as follows:
Table 13-19. 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 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.
