8.5.3.6 Data Write Command
The device can receive the function control with broadcast and non-broadcast way, which depends on the configuration of the devices. If the cascaded devices have the same configuration, broadcast is used, if the cascaded devices have the different configurations, non-broadcast is used. The MSB is always transmitted first and the LSB transmitted last. For 48-bits RGB data, the Blue data must be transmitted first, then the Green, and last the Red data.
For broadcast, the devices receive the same data. When devices recognize the broadcast command, they copy the data to the internal registers. Generally, broadcast is used for write FC0-FC13 command, LOD/LSD.
Figure 8-21 Data Write Command with
BroadcastFigure 8-22 shows the time diagram of the data write command with broadcast.
Figure 8-22 Data Write Command with Broadcast (Timing
Diagram)For non-broadcast, the devices receive the different data, the controller prepares the data as the figure shows. One pixel data is written to the corresponding device in each command. When the first device receives the END, it cuts off the last 51-bit (3 × 17 bit) data before the END, and the left are shifted out from SDO to the second device. Similarly, when the second device receives the END bytes from the former device, it cuts off the last 51-bit (3×17 bit) data before the END, and the left are shifted out to the next device. Generally, non-broadcast is used for write SRAM command (WRTGS), Details for how to write a frame data into memory bank can be found in Write a Frame Data into Memory Book.
