A non-zero number programmed in this register defines
the numerator for the ratio of the video clock to the
27MHz reference.
This register can be used for creating custom video
clock frequencies.
NOTE: Once this register is programmed, it must be
updated using bit 6 of register 16h.
The default value of this register will vary depending on
the output video standard selected.
Address 20h = bits 15-0
Address 21h = bits 31-16
