8 Determine Anti-Aliasing BW

The anti-aliasing BW (AABW) should be as low as possible to give best possible blocking. The AABW is set by the following override:

ADI_HALFREG_OVERRIDE(0,61,0xMask,0xValue). Mask is a bit mask. This is typically set to 0xF. "Value" is 4 bits where a lower value gives larger bandwidth.

Find the anti-aliasing bandwidth that gives a marginal decrease in sensitivity and select a setting value that is two settings below this. Meaning if tests using 0x09 starts to give a reduced sensitivity, 0x07 should be used.
