read/write at I/O address 3D1h with index at I/O address 3D0h set to 17h
This register sets the FRC polynomial counters, which are row and column offsets for each panel type and
are usually determined by trial and error. These values affect the quality of both 2-frame and the 16-frame
FRC algorithms and require readjustment when the horizontal or vertical parameters change, especially
when the vertical total parameter is changed.
