Hi all,

I am trying to write to a core register and the write is not working. What could be the reason?

Thanks in advance!
Christine

Hi Christine,

For its own core special function registers (CSFRs), the CPU must access them using MTCR and MFCR instructions. On the other hand, for core registers of other CPUs, the CPU should access via the SRI.
Note: For SFR registers of any CPU, this may only be accessed using load and store instructions via the SRI.

Best regards,
Mr. AURIX™
