17.4.1.1 Resources Protected by ECC

ECC is generated on the concatenation of address and write data, as shown in the figure below. The Concat box performs the concatenation of two multi-bit inputs to a single, wider output, allowing detection of address errors in the read data, i.e., reading data from the wrong address.

Detection of an ECC error sets ECC1 or ECC2 in the INTFLAGS register.

The location of the failing bit is found in the SYNDROME register. The failing address is found in the ADDR register.
