Hi everyone !

I am using LPC4088.
The question is about hardware development and more precisely how to select the pins of the LPC4088.
EMC pins are used in my development for external flash and sram.
I would like to add a LCD screen 24 bits.
The idea is to use LCD_VD[0...23] pins. I noticed that all these pins are declared in the datasheet as outputs except LCD_VD[3] and LCD_VD[7] that are inputs on pin P2.9.
Why inputs ? Is there a mistake in the datasheet ?
Data bus for TFTs is made of outputs.
Can I use P2.9 as an output for LCD purpose ?

Many thanks for help
