MSP430 Reset Button blinks LED?

$

So I am new to the MSP430 (I have the launchpad with the MSP430G2553 chip)

 

Im also pretty new to electronics and computer architecture/digital logic.

 

Anyways i have an LED (and resistor connected to 1.5 Port Pin

 

my code is here:

 

#include <msp430.h> 


void main (void){
WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer


P1DIR &= 0x00;            // reseting the P1DIR register
P1OUT &= 0x00;            // reseting the P1OUT register


P1DIR = 0x20;    // Set pins with LEDs to output , 0b00010001
P1OUT = 0x20;    // LED1 on (1.5) (Active High)


for (;;) {            // Loop forever ...
}                         // ... doing nothing
}

However I notice if I press the RESET button on the launchpad, it just blinks the LED? any ideas?

 

(Also side question....is there a better way to 'turn off' the launchpad? Theirs no option in windows 10 to disconnect it (Im connected via usb)? I stop debugging but have just pulled out the USB cable? Not sure if theirs a better way.
