Hi TI

When I use DRV8714 in my design，I developed  Offline Short Circuit and Open Load Detection (OOL and OSC) function now.

I find a strange phenomenon, which is when I enable EN_DRV and disable EN_OLSC again, Vds status do not be cleared, which is still staty last status.

My step is

1. Seting IC_CTRL1 as 0x56(disable EN_DRV and enable EN_OLSC),

2. Setting OLSC_CTRL1 as 0x99

3. Read VDS_STAT1 is 0x66.

4. Seting IC_CTRL1 as 0x96(enable EN_DRV and disable EN_OLSC)

5. Read VDS_STAT1 is 0x66.(I think it should be 0x00)
