Condition
This register controls the operation of the high side drivers.
This write-only bit enables/disables the PWMIN input pin
1 = PWMIN input controls HSx output.
0 = HSx is controlled only by SPI.
This write-only bit enables/disables the corresponding
1 = HSx switch on.
0 = HSx switch off.
This register returns the status of the high side switches
A thermal shutdown of the high side drivers is indicated by
This read-only bit signals that the high side switches are
1 = HSx Open Load detected (or thermal shutdown)
0 = Normal
