;------ Documentation Conventions --------------------------------------;
;
; The following commenting conventions are observed in this source file:
;
; If an instruction has been eliminated to save space, because it would
; effectively be a "no operation" (for example, if it would be a jump to
; the next addressable location), the assembly line is preserved, but is
; prefixed with the sequence ";==" to prevent its actual compilation.
;
; Comments on any instructions that *always* are executed with interrupts
; disabled are prefixed with ";***".
