XRGB-3 specific settings

The tested PCBs showed distortion on the top 26 lines in either B0 or B1 mode as shown in the following photograph:

This can be fixed by setting AFC to MANUAL and changing the default value to 3. It does fix the problem completely in B0, but not in B1 as shown below:

An off/on cycle is needed sometimes after changing the AFC settings.
