16. To access RAM, CE = L, UB = L, SEM = H. To access semaphore, CE = H and SEM = L. Either condition must be valid for the entire t
17. Test conditions used are Load 2.
18. This parameter is guaranteed by design, but it is not production tested.For information on port-to-port delay through RAM cells from writing port to reading port,
19. For information on port-to-port delay through RAM cells from writing port to reading port, refer to Read Timing with Busy waveform.
