DRV3901-Q1: TRG1 & 2 PIN configuration if unused

Tool/software:

Hi team, 

What is the recommendation for TRG1 & 2 PIN configuration if unused? Can we float this PIN? Because I saw there have internal pull down resistor. 

Thanks!

    Hi Ethan,

    Who is the customer and what is the application?

    How are they planning on triggering (SPI?) and where are the trigger signals coming from?

    Can you tell me their system level safety goal?

    It is a relatively weak pull down internally, external pull up/down should be used if unused.

    Best,
