Original question:

TDA4VM: How to leave the trap function

TDA4VM: Instruction to leave trap function

Part Number: TDA4VM

Hi,

We want to implement below safety mechanism, but the question is not only related to A72 as for R5F it has samilar safety mechanism. 

"A72SS.CPU5 - Illegal operation and instruction trapping"

Normarlly, illegal function will lead to a endless trap function. But as it is a test, we want to leave the trap function and run the SW as normal way. 

So is there an instrustion to leave the endless trap function?

Thanks!

Zhihua
