29. For this waveform ZZ is tied LOW.
30. When CE is LOW, CE
31. The Ignore Clock Edge or Stall cycle (Clock 3) illustrated CEN being used to create a pause. A write is not performed during this cycle
32. Device must be deselected when entering ZZ mode. See cycle description table for all possible signal conditions to deselect the device.
33. I/Os are in high Z when exiting ZZ sleep mode.
