DRV8343S-Q1EVM: The input and output of the driver chip do not match the truth table

Hi Team,

The input and output of the driver chip do not match the truth table. When outputting, the high-side MOS tube is always turned on, and the low-side MOS tube is always not turned on. The PWM output by DSP TMS320F28035PNQ corresponds to the PWM input by the drive chip.

Thanks,

Annie
