      DESCRIPTION
      The X1205 device is a Real Time Clock with clock/
      calendar, two polled alarms, oscillator compensation,
      and battery backup switch. 
      The oscillator uses an external, low-cost 32.768kHz
      crystal. All compensation and trim components are
      integrated on the chip. This eliminates several external
      discrete components and a trim capacitor, saving
      board area and component cost.
      The Real-Time Clock keeps track of time with separate
      registers for Hours, Minutes, and Seconds. The
      Calendar has separate registers for Date, Month, Year
      and Day-of-week.  The calendar is correct through
      2099, with automatic leap year correction.
