Error detection mode functionality
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:
Table 13.
Figure 18. Entering error detection mode - timing diagram
After these five CLK cycles, the device goes into “error detection mode” and at the rising
edge of the 6th CLK cycle, the SDI data are ready for sampling.
