To resume normal mode functionality, it is mandatory to apply another OE/DM2 pulse after

16 CLK pulses.

The plot in Figure 6 shows a typical example of error detection feedback. Observing the

SDO (green signal) and OE/DM2 (purple signal) it is possible to verify, respectively, the

output status and how the device returns to normal mode.
