REGISTER MAP ARCHITECTURE
The registers of the ADV7842 are controlled via a 2-wire
serial (I2C-compatible) interface. The ADV7842 has
12 maps. The IO map has a static I2C address. All other
map addresses must be programmed; this ensures no
addressing clashes on the system. Figure 9 shows the register
map architecture.
