Value:

 do \
 { \
 (mcu_critical_state) = __get_PRIMASK(); \
 __disable_irq(); \
 } \
 while (0)

Enters critical section on MCU level.

Use nrf_802154_mcu_critical_exit complementary. Consider following code:

nrf_802154_mcu_critical_state_t mcu_cs;
nrf_802154_mcu_critical_enter(mcu_cs);
// do your critical stuff as fast as possible
nrf_802154_mcu_critical_exit(mcu_cs);

Parameters

mcu_critical_state

Variable of nrf_802154_mcu_critical_state_t where current state of MCU level critical section will be stored.
