int main(void){

tmp = *(volatile uint32_t*)&RCM->SRS;

WDOG->CS = 0xA1A0 ;
tmp = *(volatile uint32_t *)&WDOG->CS;
WDOG->CS = 0xA1A0 ;
tmp = *(volatile uint32_t *)&WDOG->CS;

WDOG->TOVAL = 0x400;
WDOG->WIN = 0xFF;

tmp = *(volatile uint32_t *)&WDOG->TOVAL;
tmp = *(volatile uint32_t *)&WDOG->WIN;
while(*(volatile uint32_t *)&WDOG->CNT < 260){

};

INT_SYS_DisableIRQGlobal();
INT_SYS_DisableIRQ(WDOG_EWM_IRQn);
tmp = *(volatile uint32_t *)&WDOG->CNT;
WDOG->CNT = 0xB480A602;
while(*(volatile uint32_t *)&WDOG->CNT < 260){

};

INT_SYS_EnableIRQ(WDOG_EWM_IRQn);
INT_SYS_EnableIRQGlobal();
执行到喂狗就会复位，两次16位写入也试过了，还是不行
