DRV8908-Q1: DRV8908,slew rate How to choose

Part Number: DRV8908-Q1

Tool/software:

According to the DRV8908 document, you can see that different SR values correspond to different rates. There are a few questions about the configuration and use of SR:
1, Slew Rate was 0 or 1 in specific application scenarios, that is, in what scenarios did we configure it to 1 or 0?
2. As shown in Figure 1, when nSleep=1, SR=0 or SR=1 correspond to different leakage current sizes, how do different SRS affect the leakage current sizes?
3. When the input VM is 24V and the out port is used as a low drive, is the leakage current data shown in Figure 1 still of reference significance?
