In the data processing device, the internal registers are formed by shift registers which are connected via a test register to form a loop. If someone wishes to view the contents of a required internal register, the contents of the loop are rotated until the desired register contents appear in the test register. The contents of the loop can be rotated via a secondary path (8) without passing through the test register (6). The contents of the loop can thus be rotated while the contents of the test register can still be viewed, thus saving time. <IMAGE> |
