Feature

Functional description

Temperature Sensor (TSN)

The on-chip Temperature Sensor (TSN) determines and monitors the die temperature for

reliable operation of the device. The sensor outputs a voltage directly proportional to the die

temperature, and the relationship between the die temperature and the output voltage is fairly

linear. The output voltage is provided to the ADC12 for conversion and can be further used by

the end application.

Data processing

Feature

Functional description

Cyclic Redundancy Check (CRC)

calculator

The Cyclic Redundancy Check (CRC) generates CRC codes to detect errors in the data. The

bit order of CRC calculation results can be switched for LSB-first or MSB-first communication.

Additionally, various CRC-generation polynomials are available.

Data Operation Circuit (DOC)

The Data Operation Circuit (DOC) compares, adds, and subtracts 16-bit data. When a selected

condition applies, 16-bit data is compared and an interrupt can be generated.
