Switching WaveformsRead/Write Waveforms [18, 19, 20]
Notes:
18.For this waveform ZZ is tied LOW.
19.When CE is LOW, CE1 is LOW, CE2 is HIGH and CE3 is LOW. When CE is HIGH, CE1 is HIGH or CE2 is LOW or CE3 is HIGH.
20.Order of the Burst sequence is determined by the status of the MODE (0 = Linear, 1 = Interleaved). Burst operations are optional.
