9. X = “Don't Care.” H = logic HIGH, L = logic LOW. BWx = L signifies at least one byte write select is active, BWx = Valid signifies that the desired byte write selects
10. Table only lists a partial listing of the byte write combinations. Any combination of BW
are asserted, see truth table for details.
