This structure contains the data fields that correspond to specific fields in different registers. For a
more detailed explanation of the register fields, refer to the device datasheet.
For example, DISHIFT field of ATCFG1 is 2 bits wide (bit 28-29 of ATCFG1 register). The user
needs to set values from 0 to 3 in the dishift field of this structure. The library will take care of
writing this to the appropriate bit position of ATCFG1 register.
