LSDRV Open-Load Status Bits<br />

These bits reflect the open-load condition status on each driver related pin.<br />

This open-load monitoring will only be active if the detection function is enabled (bits LSOLEx) and the<br />

corresponding low-side driver is enabled and turned off.<br />

A delay of t HLROLDT must be granted after enabling the high-load resistance open-load detection function in<br />

order to read valid data.<br />

0 Open-load condition I LS < I HLROLDC<br />

1 Open-load condition I LS ≥ I HLROLDC<br />
