PRODUCTION DATA
Figure 9-3 gives an detail design procedure for LED display. After power on and digital signals are ready, the first step for the controller is to send the chip index command to let the devices know their identifications. Then, it sends the configuration data to the FC registers. After this, it sends the VSYNC at the beginning of each frame and also sends the data to each device. The devices display the data of last frame when the VSYNC comes and meanwhile receive the data of current frame transmitted from controller. The registers can be read at anytime of the frame.
