GPIO Speed of LPC1114FBD48/302

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.

:O

M0 and 320x480? Would strongly recommend to use at least a 72MHz M3 (LPC13xxFBD64)   :)

Without 3-stage pipeline M0 isn't a good choice  :((

How are you going to drive the GPIO's? The LPC1114 has a max clock speed of 50Mhz, so if you are expecting to drive them from code, that doesn't give a lot of time for anything else...
