Bits 8–0 are all zeros. Bits 12–9 will have the previously entered AC but this is not used and so these bits are “don’t cares”.
OSD CONTROL REGISTERS
These registers, shown in
Table 11
, control the size, position, enhanced features and ROM bank selection of up to two
independent OSD windows.
These registers are compatible to the LM1246 OSD control 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.

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.
