Table 4
Subaddress and data byte format
Notes
1.
2.
3.
See Table 3 (Subaddress byte format).
The least significant bit (LSB) of an analog alignment register is defined as AX0 (data bit D0).
Under certain conditions the nominal values lead to nominal colour signals, etc. (see notes 1 and 3 of
Chapter “Characteristics” and Figs 4 to 6).
After power-up and after internal Power-on reset of the I
2
C-bus the registers are set to the following values:
a) Control bit FPOL to logic 1.
b) Control bits DISV, DISO and BRI to logic 0.
c) All other alignment registers to logic 0 (minimum value for control registers).
Data bit.
X means don’t care but the bits are preferably set to logic 0 for software compatibility with other video ICs that have
the same slave address.
