MATOFF
DFOFF
LOGIC
LEVEL
DESCRIPTION
0 colour look-up table is active
1 colour look-up table is bypassed
0 cursor mode; input colour will be inverted
1 auxiliary cursor colour will be inserted
0 LUT loading via input data stream is inactive
1 colour and cursor LUTs are loaded via input data stream
0 input format is 8 + 8 + 8-bit 4 : 4 : 4 non-interlaced RGB or C_B-Y-C_R
1 input format is 5 + 5 + 5-bit 4 : 4 : 4 non-interlaced RGB
2 input format is 5 + 6 + 5-bit 4 : 4 : 4 non-interlaced RGB
3 input format is 8 + 8 + 8-bit 4 : 2 : 2 non-interlaced C_B-Y-C_R
4 input format is 8 + 8 + 8-bit 4 : 2 : 2 interlaced C_B-Y-C_R (ITU-R BT.656, 27 MHz clock)
(in subaddresses 91H and 94H set XPIX = number of active pixels/line)
5 input format is 8-bit non-interlaced index colour
6 input format is 8 + 8 + 8-bit 4 : 4 : 4 non-interlaced RGB or C_B-Y-C_R (special bit ordering)
0 RGB to C_R-Y-C_B matrix is active
1 RGB to C_R-Y-C_B matrix is bypassed
0 down formatter (4 : 4 : 4 to 4 : 2 : 2) in input path is active
1 down formatter is bypassed
Table 110 Subaddress FEH
DATA BYTE
CURSA
DESCRIPTION
RAM start address for cursor bit map; the byte following subaddress FEH points to the first cell to be
loaded with the next transmitted byte; succeeding cells are loaded by auto-incrementing until stop
condition
Table 111 Subaddress FFH
DATA BYTE
COLSA
DESCRIPTION
RAM start address for colour LUT; the byte following subaddress FFH points to the first cell to be
loaded with the next transmitted byte; succeeding cells are loaded by auto-incrementing until stop
condition
In subaddresses 5BH, 5CH, 5DH, 5EH, 62H and D3H all IRE values are rounded up.
