Hello,
I am having some quries related to "ERR" flag used in SPI Communication in SBC TLE9471ES.
As per manual this flag is set when
1. number of received spi clocks is not 0 or 16
2. RSTN is low and SPI frames being sent at same time
so the queries are
1. What happened if we dont take action when the ERR flag is set
2. Is there any alternative available like SPI_FAIL flag to cover this errors
Thanks in advance

Hello,
Thank you for posting your query in Infineon community.
Both SPI_Fail and ERR Flag bit are used as failure signalization bits in case of Invalid/Wrong SPI commands but with different conditions.
Refer Datasheet section 13.2 for conditions when SPI_Fail and ERR flag is set.
When ERR Flag is set due to the mentioned conditions, following SPI command is ignored.
SPI_Fail flag cannot cover ERR flag errors.
Reach out to us for any further queries.
Thanks
Anil
