CCS/MSP432P401R: dimming the led light

Part Number: MSP432P401R

Tool/software: Code Composer Studio

this code is from one of the example i found online

#include "msp.h"


int main(void) {
    void redirect(void);

    __disable_irq();

    /* set up TA0.4 to do compare */
    TIMER_A0->CTL = 0x02E4;     /* SMCLK, ID = /8, continuous mode, TA clear */
    TIMER_A0->EX0 = 7;          /* IDEX = /8 */
    TIMER_A0->CCTL[4] = TIMER_A_CCTLN_OUTMOD_6;   /* OUTMOD = toggle */
    TIMER_A0->CCR[4] = 11719;   /* toggle point 11719*/
    TIMER_A0->CCTL[4] |= 0x10;  /* enable CC interrupt */

    /* Configure P2.7 as Timer A0.4 compare output */
    P2->SEL0 |= 0x80;
    P2->SEL1 &= ~0x80;
    P2->DIR |= 0x80;

    redirect();         /* connect TA0.4 output to pin P2.1 */

    NVIC_SetPriority(TA0_N_IRQn, 3);    /* set priority to 3 in NVIC */

    __enable_irq();                     /* global enable IRQs */   
    
    while (1) {
    }
}

void TA0_N_IRQHandler(void) {
    TIMER_A0->CCTL[4] &= ~1;         /* clear interrupt flag */
    TIMER_A0->CCR[4] += 11719;       /* schedule next toggle */
}
/* This function connects the output of TA0.4 to pin P2.1 */
void redirect(void) {
    PMAP->KEYID = 0x2D52;     /* unlock PMAP */
    P2MAP->PMAP_REGISTER1 = PMAP_TA0CCR4A;  /* 23, map P2.1 to TA0.4 */

i can adjust the speed blinking but i have no idea where i can adjust the intensity of light? i want the intensity to be lower. any idea?
