Notes:
1. All byte outputs are active in read cycles regardless of the state of Byte Write Enable inputs, BA, BB, BC and/or BD.
2. Byte Write Enable inputs BA, BB, BC and/or BD may be used in any combination with BW to write single or multiple bytes.
3. All byte I/Os remain High-Z during all write operations regardless of the state of Byte Write Enable inputs.
4. Bytes “C” and “D” are only available on the x32 and x36 versions.
