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 3). Pointer

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)

●

Temperature trip point registers (read/write), including

–

Alarm temperature upper boundary,

–

Alarm temperature lower boundary, and

–

Critical temperature.

●

Manufacturer ID register (read-only)

●

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

●

Temperature resolution register (TRES) (read/write)

See Table 5 on page 17 for pointer register selection bit details.

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.
