L9305 : Error Frame in SPI Comms

Hi , 

Im facing a issue with L9305 SPI communication.

Im getting Error Frame continuously due to which i'm observing Frame counter error , crc error , Short/long frame error in the communication Faults Register.

I understand that the L9305 Chip ignores the frame if the Error Bit is "1".

Query :  

1. What are the reasons to get the Error frame?

2. How can i recover/resolve the error frames issues?

Thanks.
