DRV8718S-Q1EVM: SPI bus on the 14 pin MCU to DRV header

Part Number: DRV8718S-Q1EVM

Hello Team,

My customer is having issue in the SPI bus on the 14 pin MCU to DRV header of the EVM it is not functioning. Driving the SDI pin with a microcontroller yields wilding undefined behavior. I think I found the issue. They are fighting with the MCU over the SPI bus.

I need datasheet clarification. Datasheet: DRV87xx-Q1EVM and DRV8106-Q1EVM User’s Guide. It states: "The MCU can be disconnected from the motor driver in order to drive the latter through an external controller  by interfacing with the 14 pin header. To do so, remove the resistors between the MCU and the header that  connects the MCU to the motor driver." 

Exactly which resisters (their number designation)
Regards,
Renan
