system. Details of exception processing are provided in SECTION 8 EXCEP-
Exception processing saves the most volatile portion of the current processor
context on the top of the supervisor stack. This context is organized in a
copy of the status register, the program counter, the vector offset of the
vector, and the frame format field. The frame format field identifies the type
of stack frame. The RTE instruction uses the value in the format field to
properly restore the information stored in the stack frame and to deallocate
in Figure 4-1. Refer to SECTION 8 EXCEPTION PROCESSING for a complete
list of exception stack frames.
