This attribute selects the byte write enable mode for the BWE_A or BWE_B input bits. The default mode is PARITY_INTERLEAVED mode. In PARITY_INTERLEAVED mode, each BWE input bit enables write for a corresponding data byte and its associated parity bit. In PARITY_INDEPENDENT mode, one BWE input bit independently enables write for all eight parity bits, and each remaining BWE bit enables write for a corresponding data byte. PARITY_INDEPENDENT mode is supported for only WRITE_WIDTH = 72 bits.
