The  command define as  follows:  The  register is indicates that  user start to  transmit data,  then write to  SRAM. While  data transmission 
complete, user must send command 11H. Then chip will start to send data/VCOM for panel.   
In B/W mode, this command writes “NEW” data to SRAM.   
In B/W/Red mode, this command writes “RED” data to SRAM.
