7.3.4.7 LOD_LSD Self-Test

The TLC6C5724-Q1 device implements an LOD_LSD self-test function to check the LOD_LSD detection circuit to improve the system reliability. If the LOD_LSD detection circuit fails to detect the LED failure, the LOD_LSD self-test Function can identify and report the malfunction.

The LOD_LSD self-test function can be executed by sending the LOD_LSD self-test command. LOD_LSD_FLAG is 000b by default. After the LOD_LSD self-test command, if there is no fault on LOD_LSD detection circuit, and the LOD_LSD_FLAG value is 011b. If there are failures on the LOD_LSD detection circuits, the LOD_LSD_FLAG value is 110b, the ERR pin is pulled low, and the bit values stay unchanged until the fault is removed and an ERROR clear command is executed. If the LOD_LSD_FLAG is neither 011b nor 110b, there should be something wrong in the self-test procedure.
