S32K144 低功耗休眠问题

靖姑娘

大家好，
最近在调试S32K144 的低功耗和唤醒功能，请问有好的程序或者建议使得S32K144 进入VLPS模式吗？我的程序进入相应得指令就老是会复位一次，然后电流才下降；附上我的程序

void Power_RUN_to_STOP (void)
{
#if 0
/* Set the SLEEPDEEP bit to enable deep sleep mode (STOP) */
        S32_SCB->SCR |= S32_SCB_SCR_SLEEPDEEP_MASK;
/*select stop mode*/
        SMC->PMCTRL = SMC_PMCTRL_STOPM(0b00);
        SMC->STOPCTRL = SMC_STOPCTRL_STOPO(0b01);
        if(SMC->PMSTAT == 0x01)
        {
                asm("WFI");
        }
#else
        /* Disable the JTAG port pins */
        /* Disable Adc Pins */

        PMC->REGSC |= PMC_REGSC_BIASEN(1); // [1] CLKBIASDIS = 1 In VLPS mode, the bias current for SIRC, FIRC, PLL is disabled

        /* Disable the Fosc and Sosc from chip*/
        SCG->FIRCCSR = SCG_FIRCCSR_FIRCEN(0);
        while(SCG->FIRCCSR & (1 << 24));
        SCG->SOSCCSR = SCG_SOSCCSR_SOSCEN(0);

        S32_SCB->SCR |= S32_SCB_SCR_SLEEPDEEP_MASK|0x2; /* allow deep sleep mode0 */
        SMC->PMPROT = SMC_PMPROT_AVLP(1); /* allow very low power mode*/


        SMC->PMCTRL = SMC_PMCTRL_STOPM(2);

        if(SMC->PMSTAT == 0x01)
        {
                asm("WFI");
        }
#endif

}

void init_NVIC(void)
{

        power_cp_wakeup_set();
        INT_SYS_ClearPending(PORTE_IRQn);
        INT_SYS_SetPriority(PORTE_IRQn, 0);

        // PORTE_interrupt
        S32_NVIC-> ICPR [1] = (1 <<(63%32));
        S32_NVIC-> ISER [1] = (1 <<(63%32));
        S32_NVIC-> IP [63] = 0x00;
        //PORTE-> DFER |= (1 << 5);
}


void power_set_mode(POWER_SYS_TYPE mod)
{
    init_NVIC();
    Power_RUN_to_STOP();
}
