Temperature sensor registers

Note:

In all temperature register formats bits 0 and bits 1 are used when the resolution is more

than 10 bits. These registers show temperature data for the default 10 bits.

4.5

Manufacturer ID register (read-only)

The manufacturer’s ID (programmed value 104Ah) in this register is the STMicroelectronics

Identification provided by the Peripheral Component Interconnect Special Interest Group

(PCiSIG).

Critical temperature trip point

1. Bit 2 is LSB for default 10-bit mode.

2. If critical trip lockout bit (bit 7 of configuration register in Table 10) is set, then this register becomes read-only.

3. Depending on status of the resolution register, bit 1 may display 0.125 °C value.

4. Depending on status of the resolution register, bit 0 may display 0.0625 °C value.
