Interrupt Controller (CF1_INTC)
13.3.7
This section provides multiple views of the interrupt request assignment: a two-dimensional view of levels
and priorities within the level
(Table
The CF1_INTC module implements a sparsely-populated 7 × 9 matrix of levels (7) and priorities within
each level (9). In this representation, the leftmost top cell (level 7, priority 7) is the highest interrupt request
while the rightmost lowest cell (level 1, priority 0) is the lowest interrupt request. The following legend is
used for this table:

Reserved, must be cleared.
Vector number. Indicates the appropriate vector number.
For the SWIACK register, it is the highest-level, highest-priority request currently being asserted in the CF1_INTC
module. If there are no pending requests, VECN is zero.
For the LVLnIACK register, it is the highest priority request within the specified level-n. If there are no pending
requests within the level, VECN is 0x18 (24) to signal a spurious interrupt.

Interrupt Request Level and Priority Assignments
For remapped and forced interrupts, the interrupt source number entry
indicates the register or register field that enables the corresponding
interrupt.
