Switching Waveforms
Read/Write/Timing
[22, 23, 24]
Notes:
22.For this waveform ZZ is tied LOW.
23.When CE is LOW, CE
is LOW, CE
is HIGH and CE
is LOW. When CE is HIGH, CE
is HIGH or CE
is LOW or CE
is HIGH.
24.Order of the Burst sequence is determined by the status of the MODE (0 = Linear, 1= Interleaved). Burst operations are optional.
