DS1821 OPERATION EXAMPLE
In this example, the master device programs the DS1821 with TL = +10°C and TH = +40°C and verifies
that the data has been saved correctly. The master then programs the status/configuration register so that
the device will power-up in thermostat mode (T/R
= 1) and the thermostat output will have active high
polarity (POL = 1).
