Preliminary specification
RGB video processor with automatic
cut-off control and gamma adjust
TDA4780
Table 5
Crosstalk; note 1
Note
1.
Explanation for the cell contents of the table:
a) H = set to logic 1.
b) L = set to logic 0.
Table 6
Subaddress byte and data byte format; notes 1 and 2
Notes
1.
Explanation for the cell contents of the table:
a) L = set to logic 0.
b) X means don’t care but for software compatibility with further video ICs with the same slave address, it is
recommended to set all these bits to logic 0.
After power on reset all alignment registers are set to 01H.
The least significant bit of the analog alignment register.
