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.
