LJMP  0000H ++

     .... Erik's week or so goes by and you fix first
          problem by writing into SFR at init.

     LJMP  0000H ++

     .... Product delivers to field and after about
          six months customer complains about strange 
          behavior. Fix another SFR by software
          correction.

     LJMP  BACK_TO_CUSTOMER

     .... Your company decides to do upgrade of all 
          product shipped so far......at expense level
          that threatens to overflow the stack.

     LJMP  0000H ++

     .... Another problem found ... then after many
          manhours of work...it seems that under some 
          strange combination of conditions this
          microcontroller will not software re-init
          properly without a power cycle. Some state 
          in the onboard CAN controller I guess that
          can only be recovered via a real hard reset.

     SJMP  WHAT_CAN_DO ???  Hey...are we there yet??
