Hello every one:
Recently,I have some problems on RUN and VLSP mode configuration, I am the following information is correct:
1. S32K144 chips do not have CAN RXD wake function module
2. Before enter VLSP mode, need to configure the RTC CLOCK module
and The following is my adopted the SDK software configuration module:
static void gpio_port_int_init(void)
{
INT_SYS_EnableIRQ(PORTB_IRQn);
INT_SYS_InstallHandler(PORTB_IRQn, &gpio_portb_irq, (isr_t *)0);
INT_SYS_EnableIRQ(PORTD_IRQn);
INT_SYS_InstallHandler(PORTD_IRQn, &gpio_portd_irq, (isr_t *)0);
INT_SYS_EnableIRQ(PORTE_IRQn);
INT_SYS_InstallHandler(PORTE_IRQn, &gpio_porte_irq, (isr_t *)0);
PINS_DRV_SetPinIntSel(GPIO_CP_UNLOCK_PORT,GPIO_CP_UNLOCK_PIN,PORT_DMA_INT_DISABLED);
PINS_DRV_SetPinIntSel(GPIO_CP_WAKE_PORT,GPIO_CP_WAKE_PIN,PORT_DMA_INT_DISABLED);
PINS_DRV_SetPinIntSel(GPIO_CC_WAKE_PORT,GPIO_CC_WAKE_PIN,PORT_DMA_INT_DISABLED);
PINS_DRV_SetPinIntSel(GPIO_VCU_WAKE_PORT,GPIO_VCU_WAKE_PIN,PORT_DMA_INT_DISABLED);
}
void init_NVIC(void)
{
PINS_DRV_SetPinIntSel(PORTE,5U,PORT_INT_RISING_EDGE);
}
void Power_RUN_to_STOP (void)
{
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");
}
}
void power_set_mode(POWER_SYS_TYPE mod)
{
if(mod == POWER_SYS_SLEEP)
{
init_NVIC();
//power_can_wakeup_set();
POWER_SYS_SetMode(POWER_SYS_VLPS, POWER_MANAGER_POLICY_AGREEMENT);
}
}
