4.4.1.7 Status Register 4 (0x00000210)
Status Register 4 (Figure 4-46) provides status on the QMSS PKTDMA Starvation Interrupts managed by the INTD. Reading this register returns a 1 bit for each interrupt that has been triggered. Writing to the register causes an interrupt to be triggered for each set 1 bit just as if the corresponding input interrupt had arrived.
