*1: It may write date into any address location 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 Transition Time (tT) at AC testing is 5 ns as shown below. If actual tT is longer than 5 ns, it may violate
AC specification of some timing parameters.
