17.2.4 Vectored interrupt block
There are 16 vectored interrupt blocks. The vectored interrupt blocks receive the IRQ
interrupt requests and set VectIRQx if the following are true:
• the selected interrupt is active
• the selected interrupt is the currently highest requesting interrupt.
Each vectored interrupt block also provides a VectorAddrx[31:0] output for use in the
interrupt priority block. Figure 17-5 shows a block diagram of two of the vectored
interrupt blocks.
