HSDRV High-Load Resistance Open-Load Detection Enable
These bits enable the measurement function to detect an open-load condition on the related high-side driver
operating on high-load resistance loads. If the high-side driver is enabled and its gate is not being driven by the
selected source, then the high-load resistance detection circuit is activated when this bit is set to ‘1’.
0 high-load resistance open-load detection is disabled
1 high-load resistance open-load detection is enabled
HSDRV Enable —
These bits control the power supply of the related high-side driver circuit.
0 High-side driver supply is disabled
1 High-side driver supply is enabled
