16.6.2.2 CRC-Coprocessor Settings
For the CRC-Coprocessor the following parameters may be configured:
The CRC polynomial for the 8-bit CRC is fixed to
The CRC polynomial for the 16-bit CRC is fixed to
16.6.2.3 Status Flags of the CRC-Coprocessor
The status flag CRCReady indicates, that the CRC-Coprocessor has finished processing of all data bytes
found in the FIFO buffer. With the CRCReady flag setting to 1, an interrupt is requested with TxIRq being set.
This supports interrupt driven usage of the CRC-Coprocessor.
When CRCReady and TxIRq are set to 1, respectively, the content of the CRCResultLSB- and
CRCResultMSB-register and the flag CRCErr is valid.
The CRCResultLSB- and CRCResultMSB-register hold the content of the CRC register, the CRCErr flag
indicates CRC validity for the processed data.
16.7 Error Handling during Command Execution
If any error is detected during command execution, this is shown by setting the status flag Err in the
PrimaryStatus Register. For information about the cause of the error, the µ-Processor may evaluate the
status flags in the ErrorFlag Register.
