MSP430 : Hello World LED Blink program

This is my first program to blink all LEDs connected on PORT3 of MSP430 onboard TI MSP430FR5739 experimenters board.

/******************************************************************
 * This is my first project on my MSP430FR5739 experimenter board.
 * In this project I will attempt to blink all onboard LEDs which 
 * are connected to Port 3.
 * Pseudo code as follows
 * 1. Initialise port 3 as an output port.
 * 2. Set Port 3 to digital low.
 * 3. Initialise Loop
 * 4. Set Port 3 to Digital High
 * 5. Delay (Hold State).
 * 6. Set Port 3 to Digital Low
 * 7. Delay (Hold State).
 * 8. Loop End
