6ES5 945-7UA21   CPU 945 for S5-115U, 384 Kbyte                             

                                                                            

                                                                            

                                                                            

When accessing with L SW and an uneven parameter (e.g. L SW1) as            

well as with LRW and an uneven basic address (e.g. MBR E0001,               

LRW 0), the CPU may enter an undefined state.                               

                                                                            

In view of the above, access to uneven addresses with these ope-            

rations is no longer allowed (does not affect L SY and L SD).
