+function AVRUARTSetup(mode, baudrate, stopbits, parity)
+// Function to Setup Serial Communication i.e UART or USART in ATmega16.
 // Description
-//     This function sets prescalr for timers. 'timer' decides which of the 
-//     three (0,1,2) timers available to be used. The 'prescalar' is needed for 
-//     deciding timer clock. Select appropriate prescalar depending on MCU clock
-//     and requirement.
-//
+//        This function Setup the UART or USART for Serial Communicaion between ATmega16 
+//        and different micro controllers or between ATmega16 and Computer.   
+// 
+// Parameters
+//     mode : 
+//           0 for Asynchronous Normal mode
+//           1 for Asynchronous Double Speed mode
+//           2 for Synchronous mode
+//    
+//     baudrate : Enter one of the following available baudrates
+//                2400 , 4800 , 9600 , 14400 , 19200 , 28800 , 38400 , 57600 ,
+//                768000 , 115200 , 230400 , 250000 , 1000000 .
 //
-// Examples
-//     AVRTimerSetup(0,1)   //Timer 0 with no scaling
+//     stopbits : 
+//               0 for one stopbit
+//               1 for two stopbits
 //
+//     parity : 
+//             0 for parity disabled
+//             1 for even parity    
+//             2 for odd parity
+// 
+//Examples
+//     AVRUARTSetup(0,9600,0,0); //This function will enable UART Communication for ATmega16

+// 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'.     
+//
+// Examples
+//     AVRDigitalPortSetup(1,0);  //this function will PortA as input Port
+//

-// Function to initialise uart interface of AVR
-//
-// Calling Sequence
-//     u8AVRUARTSetups(uint8 mode, uint8 baudrate, uint8 stopbits, uint8 parity)
-//
-// Parameters
-//     mode : Mode of usart interface (0-Normal mode, 1-Double speed mode, 
-//							2-Synchronous master mode)
-//     baudrate : Baudrate for communication. Refer AVRPeripheralUART.h 
-//							for available options) 
-//     stopbits : No. of stopbits (0-1) for stopbits 1 and 2 resp.
-//	   parity: set parity bit. (0-disabled, 1-Even parity, 2-Odd parity)	
-//
-//
-// Description
-//	   This function initialises uart interface for AVR. Available modes are 
-//	   Normal mode (0), Double speed mode (1), Synchronous master mode(2). 'baudrate' 
-//	   decides baudrate for communication. For baudrate settings, variable 
-//	   'XTAL_FREQUENCY' is required. 'stopbits' sets no of stopbits for data 
-//	   packet. 0 for 1 stopbit and 1 for 2 stopbits. 'parity' decides parity bit
-//	   for communication. 0 for disabling parity bit, 1 for even parity and 2 
-//	   for odd parity.  	     
-//
