Group data is based on the program data (timing data and pattern data combination).
Each interface has small group data. In the below figure, A, B …L indicates each interface.
These small groups are combined to be a large group. In the below figure, Group 1, … 99 indicates big groups.
USER KEY BLOCK data stands for PATTERN and TIMING data assigned to PATTERN Select Key and TIMING Select

* As for the way to make and arrange USER KEY BLOCK data, see SP-8870 operating manual. As for the way to
