z Bit 2 – PCIF2: Pin Change Interrupt Flag 2
This bit is set when a logic change on any PCINT[23:16] pin has triggered an interrupt request. Provided that the I-bit in
SREG and the PCIE2 bit in PCICR are set, the MCU will jump to the corresponding interrupt vector.
The flag is cleared when the interrupt routine is executed. Alternatively, the flag can be cleared by writing a logical one to
it.
z Bit 1 – PCIF1: Pin Change Interrupt Flag 1
This bit is set when a logic change on any PCINT[15:8] pin has triggered an interrupt request. Provided that the I-bit in
SREG and the PCIE1 bit in PCICR are set, the MCU will jump to the corresponding interrupt vector.
The flag is cleared when the interrupt routine is executed. Alternatively, the flag can be cleared by writing a logical one to
it.
z Bit 0 – PCIF0: Pin Change Interrupt Flag 0
This bit is set when a logic change on any PCINT[7:0] pin has triggered an interrupt request. Provided that the I-bit in
SREG and the PCIE0 bit in PCICR are set, the MCU will jump to the corresponding interrupt vector.
The flag is cleared when the interrupt routine is executed. Alternatively, the flag can be cleared by writing a logical one to
it.
