ns *2, *3
*1 : Some data might be written into any address location if tCHWX (Min) is not satisfied.
*2 : Except for the CLK input transition time.
*3 : The Input Transition Time (tT) at AC testing is 3 ns for Asynchronous operation and 1.5 ns for Synchronous
operation respectively. If actual tT is longer than 3 ns or 1.5 ns specified as AC test condition, it may violate AC
specification of some timing parameters. Refer to " (9) AC Test Conditions".
