Hello,
What is the purpose of the RSDIS (Return Stack DISable) bit in ACTLR ?
What would be the consequence on code execution if set DISable ?
Is the software able to write this bit ?
Thanks for help
Oh!,
I'm sorry but I had been overlooked.
I think that the return stack is not frozen for Cortex-R4 and is frozen for Cortex-R5.
Anyway, it would not a big issue because the return stack pointer is invisible.

Yasuhiko Koumoto.
