Command Register (CR)
T he ADV473 has an internal command register (CR). T his reg-
ister is 8 bits wide, CR0–CR7 and is directly mapped to the
MPU data bus on the part, D0–D7. T he command register can
be written to or read from. It is not initialized, therefore it must
be set. Figure 4 shows what each bit of the CR register controls
and shows the values it must be programmed to for various
modes of operation.
Color Modes
T he ADV473 supports four color modes, 24-bit true-color,
15-bit true-color, 8-bit true-color and 8-bit pseudo-color. T he
mode of operation is determined by the S0 and S1 inputs, in
conjunction with CR7 and CR6 of the command register. S0
and S1 are pipelined to maintain synchronization with the video
data. T able III illustrates the modes of operation.
