Part Number: MSP430FR5969
Hello TI Team,
I have a question, I am flashing an LED ON/OFF code into the MSP430FR5969 but when the power switches OFF the MSP does not retain the code like I again have to reflash it. How can I save the code in the MSP so that everytime it rebots, It should execute the code.
Thank you!
Best regards,

#include <msp430.h>
int main(void)
{
WDTCTL = WDTPW | WDTHOLD; // Stop WDT
// GPIO Setup
P1OUT = 0;
P1DIR = 0xFF;
P2OUT = 0;
P2DIR = 0xFF;
P3OUT = 0;
P3DIR = 0xFF;
P4OUT = 0;
P4DIR = 0xFF;
PJOUT = 0;
PJSEL0 = BIT4 | BIT5; // For XT1
PJDIR = 0xFFFF;
// Disable the GPIO power-on default high-impedance mode to activate
// previously configured port settings
PM5CTL0 &= ~LOCKLPM5;
// Clock System Setup
CSCTL0_H = CSKEY >> 8; // Unlock CS registers
CSCTL1 = DCOFSEL_6; // Set DCO to 8MHz
CSCTL2 = SELA__LFXTCLK | SELS__DCOCLK | SELM__DCOCLK;
CSCTL3 = DIVA__1 | DIVS__1 | DIVM__1; // Set all dividers
CSCTL4 &= ~LFXTOFF; // Enable LFXT1
do
{
CSCTL5 &= ~LFXTOFFG; // Clear XT1 fault flag
SFRIFG1 &= ~OFIFG;
} while (SFRIFG1&OFIFG); // Test oscillator fault flag
CSCTL0_H = 0; // Lock CS registers
while(1)
{
P1OUT ^= BIT0; // Toggle LED
__delay_cycles(8000000);
