ECC generator. When NDFMCR1<ECCS>=“1”, setting this bit to “1” clears the
Reed-Solomon ECC. Note that this bit is ineffective when NDFMCR0<ECCE>=“0”. Before
writing to this bit, ensure that NDFMCR0<ECCE>=“1”.
Description of Registers
The <ECCRST> bit is used for both Hamming and Reed-Solomon codes.
When NDFMCR1<ECCS>=“0”, setting this bit to “1” clears the Hamming ECC in the
