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 7-3 must always be written to '0' (see
setting these bits to '0' may keep the device from performing to specifications.
The main registers include:
