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
