Hi, 

I am using LPC4367JBD208 controller for my application. For one of my requirement i have interfaced portE to one of my peripheral (3x8 Keypad). So for this i need to configure few portpins as input and few as output. I know through DIR register we can configure portpins as input or output BUT it can configure only upto port8. What about PORTA to PORTF. 

 

Kindly guide me with this how to achieve this.
