NOTES:
1. Port-to-port delay through RAM cells from writing port to reading port, refer to "Timing Waveform of Write Port-to-Port Read and BUSY (M/S = V
2. To ensure that the earlier of the two ports wins.
3. t
4. To ensure that the write cycle is inhibited on port 'B' during contention with port 'A'.
5. To ensure that a write cycle is completed on port 'B' after contention with port 'A'.
6. 'X' in part number indicates power rating (S or L).
