SD1210
A set of four control registers are used to generate output signal when there is no input
signal available to the SD1210 or the input signal is beyond the acceptable ranges.
This operation mode is called standalone mode, which is very important for the end
users when they accidentally select an input mode beyond the acceptable range of the
SD1210 or when the input cable connection becomes loose for any reason. System
manufacturers can display appropriate OSD warning messages on the LCD panel to
notify the users about the problem.
