Adaptive Filter Control Application
Figures 45 and 46 show typical signals to be processed by the
adaptive filter control block.
The following register settings were used to obtain the results
shown in Figure 46, i.e., to remove the ringing on the Y signal.
Input data was generated by an external signal source.

When changing the adaptive filter mode to Mode B [Address 15h,
Bit 6], the following output can be obtained:
The adaptive filter control can also be demonstrated using the
internally generated cross hatch test pattern and toggling the
adaptive filter control bit [Address 15h, Bit 7].
