*1 : Some data might be written into any address location if tCHWX(Min) is not satisfied.
*2 : Must satisfy tCHH(Min) after tC2LH(Min).
*3 : Requires Power Down mode entry and exit after tC2HL.
*4 : The Input Transition Time (tT) at AC testing is 5ns as shown in below. If actual tT is longer than 5ns,
each AC specification must be relaxed accordingly.
