TLC5971: TI LED Driver

Part Number: TLC5971

Hi 

1. As shown in the figure above, if SCKI is selected as GS Reference CLK for EXTGCK, can SCKI not be stopped for too long to avoid incorrect color scale scanning?

2. As shown in the figure above, when OUTTMG = ‘0’, is the selected CLK also GS Reference CLK?

3. As shown in the figure above, can you tell me the generation of Internal Latch, why is there such a big error of 2.74ms~666ns?

4. Does the yellow font mean that after the Internal Latch is completed, you need to wait at least 1.34us before downloading the SDI data so that it will not be accidentally done?

5. In addition! If you continuously send 20 Driver data, do you not need to wait for Internal Latch and 1.34us, just send 20*224bit data continuously?

6. Someone told that this Driver has a single-wire SDI method for data transmission (SCKI is not required), but it is not found in the datasheet. Does it have this function? If so, how to set it?
