ADV7160/ADV7162
ADV7160/ADV7162 INITIALIZATION
After power has been supplied, the ADV7160/ADV7162 must be initialized. The Mode Register and Control Registers must then
be set up. The values written to the various registers will be determined by the desired operating mode of the part, i.e., True-Color/
Pseudo-Color, 4:1 Muxing/2:1 Muxing, PLL on/off, Bypass Mode on/off etc. . . .
The following section gives a recommended initialization of the ADV7160/ADV7162 and an example of the ADV7162 operating in a
specific mode.
