Block RAM and FIFO ECC Primitive - Block RAM and FIFO ECC Primitive - UG573

When using the RAMB36E2 and the FIFO36E2 in ECC mode, the input and output pins are identical to the block RAM and FIFO primitives and tables described earlier in this document. In addition to the pin names shown there, both block RAM and FIFO primitives have pins for their use in ECC mode. Table 1 and Table 1 describe the pins used in ECC mode only. The FIFO only supports standard ECC mode and does not support the RDADDRECC output.
