In our i.mx280 custom board, we will use LCD ,and at the same time,we will boot from LCD pins(boot mode set by LCD pins). So, firstly, I want to know what the function of LCD_RS pin is in LCD module.
Then, we want to know whether it will make some effect when we both use the LCD and boot mode? and how to handle with the LCD_RS pin? Because if I need to boot from LCD pin, I should pull up the LCD_RS,but if I pull up the pin, then how to change the LCD_RS signal in LCD module?
Please give me some advice. 3Q!
