Clock to Output
Clock to Output
Setup/hold time for WREN and WRADDR are the same as standard ECC.
At time TRDCK_DI_ECC (encode-only ECC), before time T1W, write data A (hex)
becomes valid at the DI[63:0] inputs of the block RAM.
At time TRCKO_ECC_PARITY (encode-only ECC), after time T1W, ECC parity data
PA (hex) becomes valid at the ECCPARITY[7:0] output pins of the block RAM.
Encode-only ECC read timing are the same as normal block RAM read timing.
Decode-only ECC write timing is the same as normal block RAM write timing.
Decode-only ECC read timing is the same as standard ECC read timing.
