PLCC, TQFP and STQFP packages only.
Port-to-port delay through RAM cells from the writing port to the reading port, refer to “Timing Waveform of Write with Port -to-Port Read and BUSY."
To ensure that the earlier of the two ports wins.
t
To ensure that a write cycle is inhibited on port 'B' during contention on port 'A'.
To ensure that a write cycle is completed on port 'B' after contention on port 'A'.
'X' in part numbers indicates power rating (S or L).
BDD
