The DS1372 is a 32-bit binary up counter and 24-bit
down counter with a unique 64-bit ID. The counters, ID,
configuration, and status registers are accessed using
an I²C serial interface. The DS1372 includes a
SQW/active-low INT open-drain output that can output either a
square wave at one of four predefined frequencies, or it
can output an active-low signal when the 24-bit down
counter reaches 0.
