UseData structure which holds the Register configuration information for QMatrixThis structure contains the data fields that correspond to specific fields in different registers. For amore detailed explanation of the register fields, refer to the device datasheet.For example, CHLEN field of MCCFG0 is 8 bits wide (bit 8-15 of MGCFG0 register). The userneeds to set values from 0 to 255 (0xFF) in the chlen field of this structure.
