Notes: 1. For each of the terms above, if not already an integer, round to the next higher integer.
2. AL: Additive Latency.
3. MRS A12 bit defines which active power down exit timing to be applied.
4. The figures of Input Waveform Timing 1 and 2 are referenced from the input signal crossing at the
VIH(AC) level for a rising signal and VIL(AC) for a falling signal applied to the device under test.
5. The figures of Input Waveform Timing 1 and 2 are referenced from the input signal crossing at the
VIH(DC) level for a rising signal and VIL(DC) for a falling signal applied to the device under test.
