Notes:
*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 5 nS as shown in below. If actual tT is longer than 5 nS, it may violate
AC specified of some timing parameters.
