DRV8718S-Q1EVM: SPI Communication

Hello everyone,

I am using the DRV8718S-Q1 evaluation board to drive the motor through SPI commands, here I am seeing a huge difference in timing between SPI READ and WRITE operations.

When I am writing a value to the register the operation takes around 3.25us and when I am reading the value from the register the operation takes around 53us.

Is this the expected behavior over SPI? and if YES can you please let me know the reason for the timing difference for both READ and WRITE operations.

Looking forward for the quick response,

Thanks and Regards,

Dhanush B N
