Hi AURIX community,
Could you please let me know what is the meaning of the letters U, SV, E next to the description of the registers?
Thank you.

Hi,
Search your Aurix User Manual PDF for "Access Terms", you should find a table with all the abbreviations.
U -> User Mode accessible
R -> read-only
SV -> Supervisor Mode access only (not sure why there's both U and SV possible)
E -> Endinit protected (safety & CPU)

Hi Bernie,
They represent the access mode of the register as follows:
“U”: Access permitted in User Mode 0 or 1 (applicable to write and read).
“SV”: Access permitted in Supervisor Mode (applicable to write and read).
“E”: ENDINIT protected write. “E” means a write access is only allowed when ENDINIT is inactive ( for a short time window) after a correct ENDINIT password unlock sequence as descibed in the SCU chapter
“SE”: Safety ENDINIT protected write. “SE” means a write access is only allowed when safety ENDINIT is inactive ( for a short time window) after a correct Safety ENDINIT password unlock sequence as descibed in the SCU chapter
Best regards
Mr. AURIX™
