13.15.4 INTFLAGS – Interrupt Flag register
• Bit 7:2 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 1:0 – INTnIF: Interrupt n Flag
The INTnIF flag is set when a pin change/state matches the pin's input sense configuration, and
the pin is set as source for port interrupt n. Writing a one to this flag's bit location will clear the
flag. For enabling and executing the interrupt, refer to the interrupt level description. The config-
uration of VPCTRLA, virtual port-map control register A, or VPCTRLB, Virtual Port-map Control
Register B,, decides which flags are mapped. When a port is mapped as virtual, accessing this
register is identical to accessing the actual INTFLAGS register for the port.
