Supervisor call
Supervisor calls are signalled by the application code executing a supervisor call (scall) instruc-
tion. The scall instruction behaves differently depending on which context it is called from. This
allows scall to be called from other contexts than Application.
When the exception routine is finished, execution continues at the instruction following scall. The
rets instruction is used to return from supervisor calls.
