*1 : It may write some data into any address location if tCHWX is not satisfied.
*2 : Must satisfy tCHH(Min) after tC2LH(Min).
*3 : Requires Power Down mode entry and exit after tC2HL.
*4 : The input Trasition Time(tT) at AC testing is 5 ns as shown in below. If actual tT is longer than 5 ns, it may violate
AC specification of some timing parameters.
