10 Register Memory Map and Description
10.1 Register Map
Table 22 below describes the register/memory map that can be accessed through the I2C interface. It indicates the
register name, register address and the register contents.
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.
