How to clear the Access error frame in MC33774

[Chandru_8051]

Uc : ST controller

Chipset: MC33774A(SPI Version)

I can able to read and write successfully. While reading some of registers, The received data is with Access error frames. Framed packet is fine and working for the other registers but the same method is not working for some of the msg frames. For example, I tried to read the analog status and communication fault status register, communication fault succeeds and  analog fault status of messages contains 0x3FFF as register field.(Sample received data image is attached within this trail)

Access frame is occured. I tried to read the valid register content(0x422) but the resultant received data in DATA0 field is 0x425. What is the cause of this issue ? Whether I need to preconfigure some contents before Either ?

Hi,

There is a detailed description in the MC33774A full datasheet.

I hope it helps.

Hi Tomas, I had already gone through though. Why it responds with that frame though I had framed with the proper packet.
I also checked the AccessError Message, It has no error in the FEH_ACC_Err
