11.13.11 INT0MASK - Interrupt 0 Mask Register
11.13.12 INT1MASK - Interrupt 1 Mask Register
11.13.13 INTFLAGS - Interrupt Flag Register
8210B–AVR–04/10
• Bit 7:0 - INT0MSK[7:0]: Interrupt 0 Mask Register
These bits are used to mask which pins can be used as sources for port interrupt 0. If
INT0MASKn is written to one, pin n is used as source for port interrupt 0.The input sense config-
uration for each pin is decided by the PINnCTRL-registers.
• Bit 7:0 - INT1MASK[7:0]: Interrupt 1 Mask Register
These bits are used to mask which pins can be used as sources for port interrupt 1. If
INT1MASKn is written to one, pin n is used as source for port interrupt 1.The input sense config-
uration for each pin is decided by the PINnCTRL-registers.
• 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.
