This system is suitable when area constraints are high and there is no need for testing of the ECC function, or analysis of an error frequency and the location. No ECC registers are implemented. The ECC logic corrects the single bit errors before they are passed to MicroBlaze. Uncorrectable errors are signaled by asserting the LMB Sl_UE signal, which generates an exception in MicroBlaze. Parameter set is C_ECC = 1.
