4 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.
Tabl e 9 below summarizes the register map for the device. Accessing any invalid address
results in indeterminate data.
In the following sections are the detailed descriptions of the registers along with their power-
up default values. Examples are also included.
