Preliminary specication
Digital Video Encoder (EURO-DENC)
SAA7182; SAA7183
I2C-bus format
Table 5
I2C-bus address; see Table 6
Table 6
Explanation of Table 5
Notes
1. X is the read/write control bit; X = logic 0 is order to write; X = logic 1 is order to read, no subaddressing with read.
2. If more than 1 byte DATA is transmitted, then auto-increment of the subaddress is performed.

DESCRIPTION
UV2C
0
Cb/Cr data are two’s complement.
1
Cb/Cr data are straight binary. Default after reset.
Y2C
0
Y data are two’s complement.
1
Y data are straight binary. Default after reset.
FMT16
0
Selects Cb, Y, Cr, Y on 8 lines on MP port (“CCIR 656” compatible). Default after
reset.
1
Selects Cb, Cr on DP port and Y on MP port.
DISKEY
0
OVL keying enabled for Y, C and CVBS outputs. Default after reset.
1
OVL keying disabled for Y, C and CVBS outputs.
CBENB
0
Data from input ports are encoded. Default after reset.
1
Colour bar with programmable colours (entries of OVL_LUTs) is encoded.
The LUTs are read in upward order from index 0 to index 7.
