Remark : The letter "X" means dont't care.
Example : XX00X100 means.
The switch 1 is connected to Video input 5
Example : XX11X011 means.
Digital buffer 1 is at high level
Digital buffer 2 is at high level
Digital buffer 3 is at low level
The starting condition upon power-on is undetermined.
In this case 4 words of 16 bits are necessary to fix the device configuration.
In other case only one word of 16 bits is necessary to modify one configuration of the device.
