10.2 Registers Descriptions
The register descriptions are presented here in ascending order of Register Address. Some registers carry several
individual data fields of various sizes; from single-bit values (e.g. flags), upwards. Some data fields are spread across
multiple registers. After power on reset the registers will have the values indicated in the tables "Reset" column.
Please write the “Reserved” bits with their reset values.
