Power Management\n
   Idle and Powerdown modes\n
    - SFRs and on-chip data RAM retain their values.\n
\n
   Idle mode operates < 10 mAmps\n
    - Peripherals continue to operate\n
    - Resumes on any interrupt\n
\n
   Powerdown operates < 100 uAmps\n
    - Wake-up by external interrupt\n
    - Vcc can be reduced as low as 2V\n
\n
   Power Off flag used to distinguish between\n 
   'cold start' reset and 'warm start' reset.\n
