• Bit 6 – INTF0: External Interrupt Flag 0
When an event on the INT0 pin triggers an interrupt request, INTF0 becomes set (one). If the I-
bit in SREG and the INT0 bit in GICR are set (one), 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. This flag is always cleared when INT0 is configured
as a level interrupt.
