Alternate Functions of Port H
Table 13-15. Overriding Signals for Alternate Functions in PG4 and PG3
Port H is only present in ATmega3250/6450. The alternate pin configuration is as follows:
Table 13-16. Port H Pins Alternate Functions
The alternate pin configuration is as follows:
• PCINT23 – Port H, Bit 7
PCINT23, Pin Change Interrupt Source 23: The PH7 pin can serve as an external interrupt
source.
• PCINT22 – Port H, Bit 6
PCINT22, Pin Change Interrupt Source 22: The PH6 pin can serve as an external interrupt
source.
• PCINT21 – Port H, Bit 5
PCINT21, Pin Change Interrupt Source 21: The PH5 pin can serve as an external interrupt
source.
