MSP430FR5962IPNR

MSP430FR5962IPNR型号在程序运行过程使用空的flash进行数据存储，每次写入数据到flash MCU就重启，不能写入数据到flash，请帮忙提供参考代码或者相关说明文档

//MSP430FR59xx Demo - Long word writes to FRAM
//
//Description: Use long word write to write to 512 byte blocks of FRAM.
//Toggle LED after every 100 writes.
//NOTE: Running this example for extended periods will impact the FRAM
//endurance. MPU is also enabled by default in CCS.
//MCLK = SMCLK = default DCO
