There are three types of ECC operation: standard, encode only, and decode only. The
standard ECC mode uses both the encoder and decoder.
The various modes of ECC operation in both block RAM and FIFO are shown in
Figure 4-31
supplied by the user. The FIFO WRADDR and RDADDR addresses are generated
internally from the write counter and read counter.
