用LaunchPad对MSP43G2553的flash写入数据，掉电后读取的数据不对

        LaunchPad + MSP43G2553，Flash（Information Memory ：Segment D【0x1000 - 0x107F】）

        通过串口和编程线，发送命令给MCU，MCU程序接到指令后处理。

        先擦除Segment D，然后把数据写入地址0x1000到0x1007。

        读取地址0x1000到0x1007，通过串口返回的数据显示数据已经写入Flash。

        拔掉LaunchPad的编程线，LaunchPad电源灯灭。

        插上LaunchPad的编程线，LaunchPad电源灯亮。

        通过串口和编程线发送读取命令，串口返回数据显示读取的数据发生了变化。

        请问这个过程中间那里有问题？

FLASH擦除

unsigned char *e_address;
e_address = (unsigned char *)0x1000;

while(FCTL3 & BUSY);

FCTL2 = FWKEY + FSSEL0 + FN4;
FCTL1 = FWKEY + ERASE;
FCTL3 = FWKEY;

*e_address = 0;

while(FCTL3 & BUSY);

FCTL1 = FWKEY;
FCTL3 = FWKEY + LOCK;

FLASH写入

unsigned char *w_address;
w_address = (unsigned char *)0x1000; //可以是0x1001、0x1002到0x1007

while(FCTL3 & BUSY);

FCTL2 = FWKEY + FSSEL0 + FN4;
FCTL1 = FWKEY + WRT;
FCTL3 = FWKEY;

*w_address= F_WriteValue;

while(FCTL3 & BUSY);

FCTL1 = FWKEY;
FCTL3 = FWKEY + LOCK;
