Map Descriptor Example: Read Data and Keep History

This Map Descriptor allows the storage of data history. The driver divides the Data Array into sections corresponding to the number of HCSR_Data_Stages.
Current data (stage1) will be stored in the first section and oldest (last stage) data will be stored in the last section in the Data array. Data will be shifted to
next Stage only on change.
