Cyclic Redundancy Check (CRC)

calculator

The Cyclic Redundancy Check (CRC) calculator 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. The snoop

function allows monitoring reads from and writes to specific addresses. This function is useful

in applications that require CRC code to be generated automatically in certain events, such as

monitoring writes to the serial transmit buffer and reads from the serial receive buffer. See

section 33, Cyclic Redundancy Check (CRC) Calculator in User’s Manual.

Data Operation Circuit (DOC)

The Data Operation Circuit (DOC) compares, adds, and subtracts 16-bit data. See section 41,

Data Operation Circuit (DOC) in User’s Manual.
