MSP430FR6989 Application: Stopwatch

This application solidified ones understanding of the timer module, interrupts, ISR, and low power modes.

Programming Approach
After button S1 was set to start and stop then the clear action when button 1 was held for 0.5 seconds was programmed. Finally, S2 button press and hold would fast forward and S1 button press and hold with S2 will rewind the time. This all was programmed utilizing Timer ISR and Button ISR working with the LCD display. The liquid crystal segments were written to appropriately to reflect the given time.
