SCALL – Supervisor Call
Architecture revision:
Architecture revision1 and higher.
Description
The scall instruction performs a supervisor routine call. The behaviour of the instruction is
dependent on the mode it is called from, allowing scall to be executed from all contexts. Scall
jumps to a dedicated entry point relative to EVBA. Scall can use the same call convention as
regular subprogram calls.
