description:
|
|
The ADV7180 family may have up to three register maps. All chips have
|
|
the main register map. The availability of the CSI and VPP register maps
|
|
depends on the chip variant.
|
|
|
|
The addresses of the CSI and VPP register maps are programmable by
|
|
software. They depend on the board layout and other devices on the I2C
|
|
bus and are determined by the hardware designer to avoid address
|
|
conflicts on the I2C bus.
