Phase one: entering error detection mode
From the “normal mode” condition the device can switch to “error mode” by a logic
sequence on the OE/DM2 and LE/DM1 pins, as shown in the following table and diagram:

After these five CLK cycles, the device goes into the “error detection mode” and at the 6^th
rising edge of the CLK, the SDI data are ready for sampling.
