/* "The INTC collects interrupt requests from the peripherals, prioritizes
|
|
* them, and delivers an interrupt request and an autovector to the CPU. The
|
|
* AVR32 architecture supports 4 priority levels for regular, maskable
|
|
* interrupts, and a Non-Maskable Interrupt (NMI)."
|
|
*
|
|
* "The INTC supports up to 64 groups of interrupts. Each group can have up
|
|
* to 32 interrupt request lines, these lines are connected to the peripherals.
|
|
* Each group has an Interrupt Priority Register (IPR) and an Interrupt Request
|
|
* Register (IRR). The IPRs are used to assign a priority level and an autovector
|
|
* to each group, and the IRRs are used to identify the active interrupt request
|
|
* within each group. If a group has only one interrupt request line, an active
|
|
* interrupt group uniquely identifies the active interrupt request line, and
|
|
* the corresponding IRR is not needed. The INTC also provides one Interrupt
|
|
* Cause Register (ICR) per priority level. These registers identify the group
|
|
* that has a pending interrupt of the corresponding priority level. If several
|
|
* groups have a pending interrupt of the same level, the group with the lowest
|
|
* number takes priority."
