SOFTWARE REGISTER RESET
Writing to register 11111 will cause a register reset, resetting all register bits to their default values.
The device will be held in this reset state until a subsequent register write to any address is
completed.

WM8766 can be configured using the Control Interface. All unused bits should be set to ‘0’.
