Hi all,
I have a project using LPC1114FBD48/302. I would like to use the GPIOs to drive a i8080 system LCM (320 x 480, 262k color).
The LCM is using the LCD Driver IC ILITEK ILI9488. It requires 10-20MHz speed.
So I need to use the GPIOs to generate data 0-15(16bits), Read and Write CLK. Can the LPC1114FBD48/302 GPIOs support 10-20MHz speed?
What is the max speed of the GPIO?
What is the range of speed for the GPIO that I can assign?

Thanks.
