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 Table 2). Pointer

register bits 7 - 4 must always be written to '0'. This must be maintained, as not setting these

bits to '0' may keep the device from performing to specifications.

The main registers include:

●

Capability register (read-only)

●

Configuration register (read/write)

●

Temperature register (read-only)

●

Alarm temperature trip registers (read/write), including

–

Alarm temperature upper boundary,

–

Alarm temperature lower boundary, and

–

Critical temperature.

●

Manufacturer’s ID register (read-only)

●

Device ID and device revision ID register (read-only)

●

Temperature resolution register (TRES) (read/write)

Note:

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.
