7.5.4.2 Data set 1 in DP interface
The content of DS1 for DP interface contains the same information as DS0 because certain CPUs
rst request DS1 for diagnostic purposes. If DS1 is rejected by DP interface, the CPU does not
request any further diagnoses. Diagnostics bits that are not within the scope of DS0 always
remain set to 0.
