HI support team.

Which register should be used to set SPI_FLT_REP?
I can't find it in the datasheet.

What is the default value of SPI_FLT_REP?

Best Regards,

Hi Higa-san,

We will need to discuss this more with the team and get back to you. This bit was changed to a reserved bit, and I need to understand the background on the reserved bit.

Hi Higa-san,

The SPI_FLT_REP bit is marked as reserved in the datasheet and it is defaulted to 1, meaning that SPI errors are not reported on nFAULT or in the SPI_FLT bit. It may be another week and a half till I know the full background on this since the main colleague who is familiar with this currently on vacation.

Hi Higa-san,

I don't have any update yet, the coworker who is familiar with the background on this has been out of office the past couple weeks. I will try to see if I can get a response by the end of this week. Regarding the information I have received so far it looks like that bit is reserved and the default is to disable SPI fault reporting.

Hi Higa-san,

I got confirmation on this issue: although the datasheet shows this bit as reserved, it was not intended to be reserved. We will update the datasheet to reflect this. The SPI_FLT_REP bit is located at bit 1 of the CONTROL_3 register. Setting this bit to 0 will enable SPI fault reporting on the nFAULT pin, and setting the bit to 1 will result in the SPI fault reporting to be disabled. Thank you for your patience in waiting for a response!
