LIU[8:1]:
The LIU[8:1] register bits allow software to determine which octant’s LIU(s) is/are producing
an interrupt on the INTB output pin. A logic 1 indicates an interrupt is being produced from
the corresponding octant.
Reading this register does not remove the interrupt indication; within the corresponding
octant, the corresponding block’s interrupt status register must be read to remove the
interrupt indication.
