range address with no M_CS pin selected occurs on a SPARC write the
cycle is aborted and a host error interrupt is generated. In either case,
error status is stored in this register as described below.
When a time-out, SD/Secondary bitstream conflict or master address
with no M_CS pin selected occurs on an async master DMA cycle, the
entire transfer is aborted and the GO bit is cleared, which will cause a
Master DMA completion interrupt. Master DMA completion interrupt
handlers should check this register to see if the DMA transfer completed
normally.
