The register contains interrupt status flags. Each flag is associated with a specific interrupt

engine. It is set when the associated interrupt engine triggers. The setting of latch_int<3:0>

controls if the interrupt signal and hence the respective interrupt flag will be permanently

latched, temporarily latched or not latched. The interrupt function associated with a specific

status flag must be enabled.
