served after it is found.
Module Indication registers of the interrupting link are read. The Interrupt
Module Indication bits will be ‘1’ if there are interrupts in the correspond-
ing function block. To find the eventual interrupt sources, the Interrupt
Indication and Status bits in the block are polled if their Interrupt Enable
bits are enabled. Then the sources are served after they are found.
