7.3.5.3.2 Read LED Open Information

The LOD readback function must be enabled before read LED open information. This function is enabled by LOD_LSD_RB (see FC3 for more details).

Figure 7-10 shows the steps to read LED open information. Wait at least one sub-period time between Step2 and Step3 command.
