The IC incorporates an addressable time counter and an
addressable alarm register for minutes, hours, days and
months. Three special control/status flags, COMP, POWF
and NODA, are also available. Back-up for the clock during
supply interruptions is provided by a 1.2 V nickel cadmium
battery. The time base is generated from a 32.768 kHz
crystal-controlled oscillator.
