SIGNAL ENHANCEMENT REGISTER CONTROLS

The SE1 ‘enable’ bits are described in Table 13. Note that other control fields must also be

determined and written to the WM8946 using WISCE™ or other tools. The registers described below

only allow the sub-blocks of SE1 to be enabled or disabled.

Note that it is not recommended to access these control fields unless appropriate values have been

written to the associated bits in registers R65 to R98.
