/* DESCRIPTION
If the value of this flag is set to 1 in the registry, TV and LCD are not 
allowed to be mapped on the same controller. This restriction is imposed 
while booting-up, when finding a best view or validating a controller config. 
If flag is not set or set to any value other than 1 then there is no such restrictions.
