• Bit 5 – INTF2: External Interrupt Flag 2
When an event on the INT2 pin triggers an interrupt request, INTF2 becomes set (one). If the I-
bit in SREG and the INT2 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. Note that when entering some sleep modes with the
INT2 interrupt disabled, the input buffer on this pin will be disabled. This may cause a logic
change in internal signals which will set the INTF2 Flag. See
“Digital Input Enable and Sleep
Modes” on page 53
for more information.
