RE: DRV8711 losting register contents

Hi Rick,

It may caused by spike on the foot pin of SPI, maximum noise Vpk is about 0.9V, but after we replaced the DRV8711 chip lot, the noise was greatly reduced and the chip work well, the mark on the before lot is "59TG4 C9TD", it is "61TG4 ANNT" on the new lot, so what's the difference between these production lot?

Thanks!
