These bits are interrupt status indicators that identify the block that is the source of a pending
interrupt. The SPLRI/TTBI bit will be logic one if either the SPLR or the TTB block has
produced the interrupt. The RBOCI/PRGDI bit will be logic one if either the RBOC or PRGD
block has produced the interrupt. The FRMRI/LOFI will be logic one if either the FRMR (J2,
E3, or T3 - whichever one is enabled) or the E3, T3, or J2 Extended LOF signal (FRMLOFI
from Register x9CH) is the source of the interrupt. This register is typically used by interrupt
service routines to determine the source of a S/UNI-JET interrupt.
