Phase one: “entering error detection mode“
From the “normal mode” condition the device can switch to “error detection 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 CLK, the SDI data are ready for sampling.
