Part Number:TPIC84000-Q1
Hi team,
The customer is using TPIC84000-Q1. First, the customer needs some code routine. Then I provide the code routine that Darren Rollman provided.
Darren Rollman provided the code routine link is : 
Please check the attachment for the code routine. Now the customer refers to the code routine to use the TPIC84000-Q1 device to
communicate with MCU through SPI. The SPI commuincation code is as below. The customer would like to verify if the SPI communication is fine.
Would you support the issue?
The SPI commuincation:
