Any registers in the range of 0x8420–0x8426 are for National Semiconductor internal use only and should not be written to under
application conditions.

PREAMPLIFIER CONTROL
These registers, shown in Table 12, control the gains, DAC outputs, PLL, horizontal and vertical blanking, OSD contrast and DC
offset of the video outputs. Registers 0x8430–0x8437 are compatible to the LM1246 Registers. Any bits marked as “X” are
reserved and should be written to with zeros and should be ignored when the register is read. Additional register detail is provided
in the Control Register Definitions Section, later in this document.
