Register DM provides programmable control of the CH7012 VGA to TV display mode, including input resolution
(IR[2:0]), video output standard (VOS[1:0]), and scaling ratio (SR[2:0]). The mode of operation is determined according
to
Table 10
below. For entries in which the output standard is shown as PAL, PAL-B,D,G,H,I,N,N
C
can be supported
through proper selection of the chroma sub-carrier. For entries in which the output standard is shown as NTSC, NTSC-
M,J and PAL-M can be supported through proper selection of VOS[1:0] and chroma sub-carrier.
