XMEGA D4 has a Programmable Multi-level Interrupt Controller (PMIC). All peripherals can
define three different priority levels for interrupts; high, medium or low. Medium level interrupts
may interrupt low level interrupt service routines. High level interrupts may interrupt both low-
and medium level interrupt service routines. Low level interrupts have an optional round robin
scheme to make sure all interrupts are serviced within a certain amount of time.
The built in oscillator failure detection mechanism can issue a Non-Maskable Interrupt (NMI).
When an interrupt is serviced, the program counter will jump to the interrupt vector address. The
interrupt vector is the sum of the peripheral’s base interrupt address and the offset address for
specific interrupts in each peripheral. The base addresses for the XMEGA D4 devices are
shown in
described for each peripheral in the XMEGA A manual. For peripherals or modules that have
only one interrupt, the interrupt vector is shown in
address.
