Temperature sensor registers
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 the :
● 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’s ID register (read-only)
● Device ID and device revision ID register (read-only)
● Temperature resolution register (TRES) (read/write)
