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.
PCINT20 – Port H, Bit 4
PCINT20, Pin Change Interrupt Source 20: The PH4 pin can serve as an external interrupt source.
PCINT19– Port H, Bit 3
PCINT19, Pin Change Interrupt Source 19: The PH3 pin can serve as an external interrupt source.
PCINT18 – Port H, Bit 2
PCINT18, Pin Change Interrupt Source 18: The PH2 pin can serve as an external interrupt source.
PCINT17/SEG – Port H, Bit 1
PCINT17, Pin Change Interrupt Source 17: The P1 pin can serve as an external interrupt source.
PCINT16 – Port H, Bit 0
PCINT16, Pin Change Interrupt Source 16: The PH0 pin can serve as an external interrupt source.
Table 14-17 and Table 14-18 relates the alternate functions of Port H to the overriding signals shown in Figure 14-
Table 14-17. Overriding signals for alternate functions in PH7:PH4.
