INTFLAGS - Interrupt Flag Register
• Bit 7:2 - Reserved
These bits are reserved and will always be read as zero. 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 according to the pin's input sense configuration
occurs, 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 configuration of "VPCTRLA - Virtual Port-map Control Register A" or "VPCTRLB - Virtual
Port-map Control Register B" decides which the flags mapped. When a port is mapped as vir-
tual, accessing this register is identical to accessing the actual INTFLAGS register for the port.
