Alternate Functions of Port H
Table 13-23. Overriding Signals for Alternate Functions in PG3:0
Port H is only present in ATmega3290/6490. The alternate pin configuration is as follows:
Table 13-24. Port H Pins Alternate Functions
The alternate pin configuration is as follows:
• PCINT23/SEG – Port H, Bit 7
PCINT23, Pin Change Interrupt Source 23: The PH7 pin can serve as an external interrupt
source.
SEG, LCD front plane 36.
• PCINT22/SEG – Port H, Bit 6
PCINT22, Pin Change Interrupt Source 22: The PH6 pin can serve as an external interrupt
source.
SEG, LCD front plane 37.
