From a software prospective, the MAX6683 appears as
a set of byte-wide registers that contain voltage and tem-
perature data, alarm threshold values, or control bits.
The device employs five standard SMBus protocols:
write byte, read byte, read word, send byte, and
receive byte (Figures 2, 3, 4).
The device address can be set to one of four different
values by pin strapping ADD to GND, SDA, SCL, or
