5.1.10 ECC_EN and ECC_BYPASS

The ECC operation is only allowed in two-port mode when the width of both ports is greater than 20 bits.

• ECC_EN = 0—disable ECC.
• ECC_EN = 1, ECC_BYPASS= 0—enable ECC Pipelined.
  • ECC Pipelined mode inserts an additional clock cycle to read-data. In addition, write-feed-through, and read-before-write modes add another clock cycle to read-data.
• ECC_EN = 1, ECC_BYPASS= 1—enable ECC Non-pipelined.
