NOTES:
1. Port-to-port delay through RAM cells from writing port to reading port, refer to "Timing Waveformof Write with Port-to-Port Read and
BUSY (M/S = VIH)".
2. To ensure that the earlier of the two ports wins.
3. tBDD is a calculated parameter and is the greater of 0, tWDD – tWP (actual) or tDDD – tDW (actual).
4. To ensure that the write cycle is inhibited on Port "B" during contention on Port "A".
5. To ensure that a write cycle is completed on Port "B" after contention on Port "A".
6. 'X' in part numbers indicates power rating (S or L).
