The slave bridge monitors AXI read and write burst type inputs to ensure that only the INCR (incrementing burst) type is requested. Any other value on these inputs is treated as an error condition and the Slave Illegal Burst (SIB) interrupt is asserted. In the case of a read request, the Bridge asserts SLVERR for all data beats and arbitrary data is placed on the Slave AXI4-MM read data bus. In the case of a write request, the Bridge asserts SLVERR for the write response and all write data is discarded.
