TPS929120EVM: Fault response from Driver TPS929120

Part Number: TPS929120EVM

Dear,

I have been testing and building a solution for automotive applications. And I need support with the following issue.

Hardware setup as follow:

1- MCU send/receive CMD to the driver TPS929120

2- TPS929120CANEVM is used to translate UART signals into CAN physical layer

3- TPS929120EVM is connected to the CAN bus 

I have written into register IOUT0 (00h) value (05h)

when I read from the same register, I receive incorrect data always (00h) although the CRC is correct and relevant to value (50h) which has been written into the register. That means that the register has been written successfully but the data byte received is not correct. 

Here is logic analyzer on Tx and Rx on TPS929120CANEVM
