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. Unused bits are ‘don't care’ and writing either 0 or 1 will not affect any function
of the device. After power on reset the registers will have the values indicated in the tables “Reset” column.
