10.1

Phase one: “entering in detection mode“

From the “Normal Mode” condition the device can switch to the “Error Mode“ by a logic

sequence on the OE/DM2 and LE/DM1 pins as showed in the following table and diagram:

After these five CLK cycles the device goes into the “Error Detection Mode“ and at the 6th

rise front of CLK the SDI data are ready for the sampling.
