REGISTER MAP
The complete register map is shown below. The detailed description can be found in the relevant text of the device description. The
WM8805 can be configured using the Control Interface. Any unused bits which are not specified should be set to ‘0’. Not all
registers can be read. Only the device ID (registers R0, R1 and R2) and the status registers can be read. These status registers
are labelled as “read only”.
