structure
Input / Output
Use
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, CHLEN field of MCCFG0 is 8 bits wide (bit 8-15 of MGCFG0 register). The user
needs to set values from 0 to 255 (0xFF) in the chlen field of this structure. The library will take
