DRV8706S-Q1EVM: Proper use of SPI registers IC_STAT_1 and IC_STAT_2

I feel that the contents of IC_STAT_1 have items that are confirmed in the same way as IC_STAT_2.
It would be helpful if you could explain with an example.

　IC_START_1　　　　　IC_START_2
　　SPI_OK　　　　　　　ADDR_FLT
　　　UV　　　　　　　　PVDD_UV
　　　OV　　　　　　　　PVDD_OV
　　　OT　　　　　　　　OTW or OTSD
