Temperature sensor registers
The temperature sensor component is comprised of various user-programmable registers.
These registers are required to write their corresponding addresses to the pointer register.
They can be accessed by writing to their respective addresses (see
register bits 7 - 4 must always be written to '0' (see
setting these bits to '0' may keep the device from performing to specifications.
The main registers include:

See
Table 3.
Registers beyond the specified (00-08) are reserved for STMicroelectronics internal use
only, for device test modes in product manufacturing. The registers must NOT be accessed
by the user (customer) in the system application or the device may not perform according to
specifications.
