DRV8889-Q1: How long time Is it required that register affect its function after capture point?

Part Number: DRV8889-Q1


Hello supporting team,

this is Ochi. I have a question about Figure 31 SPI Transaction.

Could you tell me how long time is DRV8889-Q1 needed to affect its function, after capture point?

Are there any problems to change operation mode (from disable mode to operating mode) as soon as after capture point?

Best regards,

Ochi

    Ochi-san,

    After SPI Transaction capture point, DRV8889-Q1 will execute that command immediately.  

    "change operation mode (from disable mode to operating mode)"

    Do you mean the nSLEEP pin control or DRVOFF pin control? I don't see any problem to change operation mode from disable mode to operating mode.

    Hello Wang-san,

    Thank you for supporting.

    I mean the DRVOFF pin control. And I understand DRV8889-Q1 will execute its command immediately after capture point.

    Thank you very much.

    Best regards,

    Ochi.
