DRV8311: Different test waveforms

Hi Rhea,

Thanks for the question, I will aim to provide feedback by the end of this week.

Hi Sarah,

When will the update come out?

Thanks~

Hi Rhea,

I will more time to review this info with my team. I will aim to provide an update by end of next week.

Sarah

Hi Sarah,

Will you give us feedback this week?

Hi Rhea,

Yes, I am waiting on feedback from my team and will provide a response by the end of this week.

Best,

Sarah

Hi Sarah,

Is this the team testing the data comparison? Could you please update the reply?

Thanks!

Hi Rhea,

I have a few follow up questions.

1. When looking at your settings it looks like you have it set differently from the data sheet diagram which requires PWM_OSC_SYNC=2h. You are actually using 5h.

 pwmg_ctrl_data=（0x1《10）｜（0x0 《8）｜（0x2  《5）

Can you confirm this by providing the above data in either hex or binary? This will clarify if the register is correctly set to expect the data sheet 8-11. figure.

          2. How are you measuring the HS_ON signal? Can you also provide the waveforms to include PWM_SYNC, HS_ON, and LS_ON? 

Thank you,

Sarah
