function AVRDigitalSetup(port,pin,direction)
// Function to decide direction of a digital pin on AVR
//
// Calling Sequence
// AVRDigitalSetup(port,pin,direction)
//
// Parameters
// port : port of microcontroller to be used
// pin : pin of port (mentioned above) to be used
// direction : direction to be set for pin (INPUT\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'.
//
// Examples
// AVRDigitalSetup('A',0,OUTPUT)
//
// See also
// AVRDigitalIn AVRDigitalOut
//

// Authors
// Siddhesh Wani
//
// This is curretly dummy function. It provides no functionality but is required
// for providing support for generating C code for AVR.
