generated from the ECC for written data and the ECC for read data. At this time, no special
care is needed if ECC generation and error calculation are performed serially. If these
operations need to be performed parallely, the intermediate code used for error calculation
must be latched while the calculation is being performed. The <RSECCL> bit is provided to
enable this latch operation.
