This bit controls when comb is enabled internally.
0
Comb is enabled by the internal signal COMB_EN.*
1
Comb is enabled when VAV is active.
The 15-bit register defines a horizontal scaling ratio of HSCL[14:0]/2¹⁵. Any change to this
value will become effective during the next vertical sync.

Use the set of coefficients for 75% comb.
The 14-bit register defines a vertical scaling ratio of VSCL[13:0]/2¹⁴. Any change to this value
will become effective during the next vertical sync.
