PREAMPLIFIER CONTROL
These registers, shown in
Table 14. LM1246 Preamplifier Interface Registers
, control the gains, DAC outputs, PLL, horizontal and
vertical blanking, OSD contrast and DC offset of the video outputs. The registers, shown in
Table 15. LM1246 Preamplifier
Interface Auto Size Registers
, provide measured and calculated data for the microcontroller to perform auto size and auto center
functions. 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.

TWO-COLOR ATTRIBUTE RAM
This address range (0x8440–0x8497) contains the attribute lookup tables used for displaying two-color characters. There are 16
groups of 4 bytes each according to the format shown in
Table 16. LM1246 Two-Color Attribute Registers
. The attributes are
stored starting with Color 0 (background) and each color is stored red first, green second and then blue. They may be written or
read using the following address format:
