Once entering in VLPS mode, an interrupt external input can not wake up MCU.
The PTC12 is configured as GPIO input and rising edge interrupt is enabled on it.
I configure an interrupt handler to just clear the ISF bit.
I use this code to enter in VLPS:
SMC->PMPROT |= SMC_PMPROT_AVLP(1);
/* Select VLPS mode */
SMC->PMCTRL = SMC_PMCTRL_STOPM(0b010);
/*wait for write to complete to SMC before stopping core */
dummyread = SMC->PMCTRL;
/* Enable SLEEPDEEP bit in the core */
S32_SCB->SCR |= S32_SCB_SCR_SLEEPDEEP_MASK;
/* Waiting for next interrupt will get micro in sleep mode */
The GPIO interrupt is tested and working correctelly before the MCU goes to VLPS.
So why can not wake up from VLPS? M I missing something?
