Notes:
13. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified
14. 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
15. At any given temperature and voltage condition for any given device, t
16. Test conditions used are Load 3.
17. This parameter is guaranteed but not tested.
18. For information on port-to-port delay through RAM cells from writing port to reading port, refer to Read Timing with Busy waveform.
