Hi all,

When writing CPU subregisters such as CPUx_SPROT_, ISP, BTV, BIV, DCON0 and PCON0 without ENDINIT unlocked, there is no trap. Why does this happen?


Kind regards,
Bernie

Hi Bernie,

A disallowed access to any CPU register (e.g. attempted write to read only
register, attempted user mode access to SV, attempted access to E without
Endinit, etc.) will NOT result in a Bus Error.

Best regards,
Mr. AURIX™
