CRC Calculation Circuit
Figure 1.19.1. Block diagram of CRC circuit
Figure 1.19.2. CRC-related registers
The Cyclic Redundancy Check (CRC) calculation circuit detects an error in data blocks. The microcom-
puter uses a generator polynomial of CRC_CCITT (X
The CRC code is a 16-bit code generated for a block of a given data length in multiples of 8 bits. The CRC
code is set in a CRC data register each time one byte of data is transferred to a CRC input register after
writing an initial value into the CRC data register. Generation of CRC code for one byte of data is com-
pleted in two machine cycles.
Figure 1.19.1 shows the block diagram of the CRC circuit. Figure 1.19.2 shows the CRC-related registers.
Figure 1.19.3 shows the calculation example using the CRC calculation circuit.
