DRV8910-Q1: Update timing of OUT pins

Part Number: DRV8910-Q1

Hello,

I want to confirm the update timing of OUT pins on DRV8910-Q1.

It has 10 ch high or low side switches. My customer wants to use as just a high side switch.
Is it possible to update(ON or OFF) all these 10ch OUT pins status simultaneously?

According to the register map, Ch1-Ch4, Ch5 -Ch8 and Ch-Ch10 are grouped.

So I guess 4 channles in the same register group like ch1-4 can be updated simultaneously, but channels in other group like ch1 and Ch5 can't be updated simultaneously.

Is this my understanding correct?

Regards,
Oba

    Oba,

    Your understanding is correct.  You can only write to one CTRL register at a time, so all of the channels in that register will update once the WRITE command commences.  The others will have to wait until the next WRITE command comes.  Delay should not be that long as the device supports high-speed comms.

    Regards,
