How can I do software interrupt in nRF Connect SDK v2.9.0

[Nedaa_H_Ahmed]

Hello, 
I am using nRF Connect SDK version 2.9.0, and I want to know how to perform the software interrupt.

Where can I find the driver of the software interrupt to know its APIs and use them?

It is triggered by a timer

Perhaps you can use a Zephyr timer instead?
