Notes:
11.
If data is simultaneously written and read to the same address location and tCCS is violated, the data read from the address, as well as the subsequent data
remaining in the address is undefined.
12. fMAX2 for commercial is 135 MHz. tCYC2 Min. for commercial is 7.4 ns.
13. This parameter is guaranteed by design, but it is not production tested.
14. Valid for both address and data outputs.
