First question asked Welcome!

I'm wondering if all Aurix processors feature overlay RAM for e.g. calibration, or if this is only available in certain variants like ED versions.

Hi ThePeter,

If you check RABRi(i=0-31) register, you could found the OMEM field:

Overlay Memory Select:

0-5H: Core0-5 DSPR/PSPR memory

8H: LMU

9H: EMEM

AH: EBU

...

For EMEM,  please check TC3xx ED device datasheet, and please note that i.e. TC399XX has 4096KB EMEM too, please check TC39x variants pdf if need.
