•Bit 2 – PCIF2: Pin Change Interrupt Flag 2

When a logic change on any PCINT23..16 pin triggers an interrupt request, PCIF2 becomes set

(one). If the I-bit in SREG and the PCIE2 bit in PCICR are set (one), the MCU will jump to the

corresponding Interrupt Vector. The flag is cleared when the interrupt routine is executed. Alter-

natively, the flag can be cleared by writing a logical one to it.

•Bit 1 – PCIF1: Pin Change Interrupt Flag 1

When a logic change on any PCINT15..8 pin triggers an interrupt request, PCIF1 becomes set

(one). If the I-bit in SREG and the PCIE1 bit in PCICR are set (one), the MCU will jump to the

corresponding Interrupt Vector. The flag is cleared when the interrupt routine is executed. Alter-

natively, the flag can be cleared by writing a logical one to it.

•Bit 0 – PCIF0: Pin Change Interrupt Flag 0

When a logic change on any PCINT7..0 pin triggers an interrupt request, PCIF0 becomes set

(one). If the I-bit in SREG and the PCIE0 bit in PCICR are set (one), the MCU will jump to the

corresponding Interrupt Vector. The flag is cleared when the interrupt routine is executed. Alter-

natively, the flag can be cleared by writing a logical one to it.
