function AVRDigitalPortSetup(port,direction)
// Function to decide direction of port on AVR
//
// Calling Sequence
// AVRDigitalPortSetup(port,direction)
//
// Parameters
// port : port of microcontroller to be used(1 for PORTA, 2 for PORTB,...)
// direction : direction to be set for pin (0 for INPUT, 1 for OUTPUT)
//
// Description
// Each AVR microcontroller has pins which can be configured as digital
// outputs/inputs. These are normally divided among some 'ports' (group of pins).
// User has to select one of these port and which pin of that port to be
// used as digital output/input. Also, desired direction must be specified as
// 'INPUT' or 'OUTPUT'.
//
// This is curretly dummy function. It provides no functionality but is required
// for providing support for generating C code for AVR.
//
// Examples
// AVRDigitalPortSetup(1,0); //This function will make PortA as input port
//

// AVRDigitalIn AVRDigitalOut

// Siddhesh Wani
// Ashish Kamble

disp("Error : Invalid input argument ''port'' in AVRDigitalPortSetup function.");
end
if(direction>=2) then

end
