function state = AVRDigitalIn(port,pin)
// Function to get state (high\low) of a digital input pin on AVR
//
// Calling Sequence
// state=AVRDigitalIn(port,pin)
//
// Parameters
// port : port of microcontroller to be used
// pin : pin of port (mentioned above) to be used
// Returns
// state : state of an input pin (HIGH\LOW)
//
// Description
// Each AVR microcontroller has pins which can be configured as digital
// 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 as
// digital input.
//
// Examples
// pinA0 = AVRDigitalIn(1,0) //To read state on pin 0 of port A
//
// See also
// AVRDigitalOut AVRDigitalSetup

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