This machine data is calculated only once during ramp-up; its value cannot therefore be
changed during operation.

This machine data is used to display detected CRC errors (cyclical redundancy check). The
counter information is output with every read request and is 5 bits in width (bit 4...bit 0 or
counter reading 0...31).
Note:
It cannot be guaranteed in all cases that the CRC error is assigned to the appropriate drive.
When the address is faulty, the "wrong" module indicates the error.
