How to detect wheather MCU is booting from power ON or wakeup from the standby mode?

[Yali Mobilities]

I'm using SPC58EC80 (SPC58EC DISP). I have coded the MCU for standby mode. It's working well but I have program it like wheather the MCU is booting from power ON or from standby wakeup. I have four wakeup intterupts and I want to know which wakeup interrupt is triggered the MCU to wakeup.

#include "components.h"

#include "wkpu_lld_cfg.h"

 

 

 

void int28_irq_cb(WKPUDriver *wkpup)

{

(void)wkpup;

/* Wait the SIUL2 is ready after

the exit from the SPOP0 mode.*/

while (MC_ME.PS0.B.S_SIUL == 0U)

{

;

}

 

pal_lld_clearpad(PORT_F, PF_LED3);

}

 

/*

 * Application entry point.

 */

int main(void)

{

 

uint8_t i;

 

/* Initialization of all the imported components in the order specified in

the application wizard. The function is generated automatically.*/

componentsInit();

 

/* Switch-off all LED's.*/

pal_lld_setpad(PORT_F, PF_LED1);

pal_lld_setpad(PORT_F, PF_LED2);

pal_lld_setpad(PORT_F, PF_LED3);

 

/* Enable Interrupts */

irqIsrEnable();

 

/* Configure WKPU.*/

wkpu_lld_start(&WKPUD1, &wkpu_config_wkpu_cfg);

 

/* Wait 1,5 seconds.*/

for (i = 0 ; i < 3U; i++)

{

pal_lld_togglepad(PORT_F, PF_LED1);

osalThreadDelayMilliseconds(250);

pal_lld_togglepad(PORT_F, PF_LED2);

osalThreadDelayMilliseconds(250);

}

 

/* Move the core in STANDBY0 mode.*/

if (SPCSetRunMode(SPC5_RUNMODE_STANDBY0) == CLOCK_FAILED)

{

SPC5_CLOCK_FAILURE_HOOK();

}

 

 

/* Application main loop.*/

for ( ; ; )

{

 

}

}

ease have a look at RGM module, FES and DES registers.

These registers are used to understand if the device is booting from a Power On Reser of a Functional/Destructive reset or from a Wakeup condition.
