Migration to SD functions

[Ck]

I have to update my non soft device source code to SD because now I will use Radio.

My question is if it is necessary to rewrite all functions which are in SD API. Like:

NVIC_SetPriority(ADC_IRQn, APP_IRQ_PRIORITY_LOW);
NVIC_ClearPendingIRQ(ADC_IRQn);
NVIC_EnableIRQ(ADC_IRQn);
NRF_POWER->SYSTEMOFF = 1;	
NRF_CLOCK->TASKS_HFCLKSTART = 1;
NRF_RTC1->EVENTS_COMPARE[0] = 0;
__WFI();
__WFE();
and similiar

I'm assume that SD alternate function has just some assert to control if I'm passing right arguments or so. So if I'm sure I didn't use any resources against SD, is it necessary to use strictly only SD functions?

You can see in S110_SoftDevice_Specification_v1 3.pdf there is a list of peripherals used by softdevice in "Table 23 Peripheral protection and usage by SoftDevice".

Any direct access to the protected resources while softdevice is enabled will generate hard fault by softdevice, so you must use softdevice calls to access to this resources.

Great. Now I'm not sure only with __SEV(); Can I use this instruction withih SD enabled? I'm using this in IRQ handler after event_flag is set to avoid race condition.
