DRV8873: Sample code for SPI configuration in daisy chain mode

DRV8873S-Q1EVM: Errata comment in example SPI code

Hi.

I saw in your example code (drv8873x-q1.c) for function drv8873xq1_spiInit with the comment below...

/*The errata of the DRV8873S requires enabling the internal mcu pullup */
// set internal pullup for SDO

What is this errata about?  Is this errata in a publication document?  

Best regards

    Hi Erek,

    That comment is not accurate - the datasheet describes the behavior of the pin in section 7.3.1.8 "nSLEEP as SDO Reference".  Enabling the pull-up on SDO provides a redundant reference to set the correct logic level range on SDO (3.3V or 5V).
