ON/OFF signal - MSP430F5438 Experimenter Board

Hi,

I am having some problems coding the experimenter board (MSP430F5438 Experimenter Board) to send a High and Low signal.

I am able to turn on and off the LED1 using P1.0 using the following code:

#include	"msp430x54x.h"

//this code turns the LED1 ON
void main(void)
{
	  WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer

	    
	  P1OUT |= BIT0;  // P1.0 high
	  P1SEL &= ~BIT0; // configure P6.7 for digital I/O
	  P1DIR |= BIT0; // configure P6.7 as output

	  P1OUT |= BIT0;  // P1.0 high

	   while(1); //spin forever
}

But when I decide to use an external pin in the experimenter board (for example P6.7), and I connect a multimiter to the pin,

the voltage doesn't change, it is always around 0.01 even if I am setting the pin to high. Here is the code I am using:

#include	"msp430x54x.h"

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

	  P6REN |= BIT7; // enable internal pull up, 1
	  P6OUT |= BIT7;  // P6.7 high
	  P6SEL &= ~BIT7; // configure P6.7 for digital I/O
	  P6DIR |= BIT7; // configure P6.7 as output

	  P6OUT |= BIT7;  // P6.7 high

	  while(1); //spin forever

}

What I am missing here? Thank you so much for the help.
