2.5.2. ECC Parity Flip
When the ECC Encoder Bypass (eccencbypass) port is high, the built-in ECC encoder values are XOR-ed with the 8 parity bits through the parity ports to generate a new set of encoder value. When the ECC Encoder Bypass port is low, the encoder generates the parity bits according to the data input during a write process.
The following table shows an example to construct an 8-bit data width for the parity port.
