Floating-point Exception
Coprocessor Exception
Supervisor call
The Floating-point exception is generated when the optional Floating-Point Hardware signals
that an IEEE exception occurred, or when another type of error from the floating-point hardware
occurred..
The Coprocessor exception occurs when the addressed coprocessor does not acknowledge an
instruction. This permits software implementation of coprocessors.
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.
