8.1.5.3.4 Configuration CRC Error

During normal operation the operation the Configuration is periodically checked by dedicated
FPGA internal logic. In the case of a CRC error the signal CONF_CRC_ERR is asserted to signal
the system, that FPGA logic may be corrupted.

Such an error is handled like a power failure.
