Launchpad MSP430FR5969 and External crystall HFXT 16 MHz not working

I tested the launchpad board with internal DCO and all works ok.

Then I soldered an external 16 Mhz crystal with 18pf capacitors. I'm trying to run this code to test (with an oscilloscope) if the HFTX. There is some problem because my system produce an clock event every 13ms instead of 62.5ms. The strange thing is that if I remove the crystal the system still working with the same clock period.
Someone have some example with the MSP430FR59xx family ?

Thanks

This is my code: I'm not sure about PJ configuration

#include <msp430.h>



int main(void)
{



    //SET PORT

    PM5CTL0 &= ~LOCKLPM5;       // Disable the GPIO power-on default high-impedance mode to activate previously configured port settings
    WDTCTL = WDTPW | WDTHOLD;    // Stop watchdog time
    

    //SET LED PORT

    P1SEL0=0b00000000;
    P1SEL1=0b00000000;
    P1OUT = 0;
    P1DIR = 0xFF;

     //SET HFXT PORT : not sure
    

      PJDIR = 0x00;

      PJSEL0|=BIT7|BIT6;
      PJSEL1=0x00;

    //SET CLOCK SURCE
    CSCTL0_H = 0xA5;       // Unlock CS registers
    CSCTL1_L=0b00000000;                                                   //DCO 1Mhz (not used)
    CSCTL2_L=SELS__HFXTCLK | SELM__HFXTCLK;     //SMCLK and MCLK source = HFXT
    CSCTL3_L=DIVS__1;                                                          //SMCLK/1 and MCLK/1
    CSCTL4_H = HFXTDRIVE1_H|HFFREQ1_H;               //Ser current crystal and frequence = 16Mhz

    //SET CLOCK

    TA0CCTL0 = CCIE;                                                   // TACCR0 interrupt enabled
    TA0CCR0 = 62500;                                                   // Value to compare with the timer to generate interrupt
    TA0CTL = TASSEL__SMCLK |ID__1| MC__UP;  // select SMCLK, Divide SMCLK/1, UP mode
    TA0EX0 = TAIDEX_0;                                                // DIV1 : So timer_CLK = SMCLK/1
    __bis_SR_register(LPM1_bits + GIE);               // Enter LPM0 plus ENABLE INTERRUPT




    while(1)
    {

    }
    return 0;

}
