Detection mode functionality
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:
Table 12.
Figure 17. Entering in detection timing diagram
After these five CLK cycles the device goes into the “error detection mode” and at the 6
rise front of CLK the SDI data are ready for the sampling.
