STTS751 register summary
The STTS751 uses 8-bit registers. Variables longer than 8 bits are managed in byte pairs.
For example, when reading a 10-bit temperature value (10 bits is the default resolution.) the
application must read two registers and then concatenate the upper byte with the 2 most
significant bits of the lower byte.
