1.1 芯片手册的概要信息
#资料是IMX6ULLRM.pdf
The eLCDIF block supports the following:
• Displays with an asynchronous parallel MPU interface for command and data transfer to an integrated frame buffer. (8080接口)
• Displays that support moving pictures and require the RGB interface mode (DOTCLK interface). (TFT-RGB接口)
• VSYNC mode for high-speed data transfers. (MPU+VSYNC信号)
• Digital video encoders that accept ITU-R BT.656 format 4:2:2 YCbCr digital component video and convert it to analog TV signals.
