Notes:
1. If address A1 = A2, data Q1-1 = D2-1 and data Q1-2 = D2-2. Write data is forwarded immediately as read results.
2. B2-1 and B2-2 refer to all BWx# byte controls for D2-1 and D2-2 respectively.
3. B4-1 and B4-2 refer to all BWx# byte controls for D4-1 and D4-2 respectively.
4. B6-1 and B6-2 refer to all BWx# byte controls for D6-1 and D6-2 respectively.
5. B7-1 and B7-2 refer to all BWx# byte controls for D7-1 and D7-2 respectively.
6. Outputs are disabled one cycle after a NOP.
