# silabs_s2 uses simplicity_sdk hal library, which already have by default a zero latency
# IRQs mechanism with a hardcoded value. In order to be aligned with simplicity_sdk, we
# need to activate Zero Latency IRQ in Zephyr by default. The level (2) depends on the
# hardcoded value in simplicity_sdk (CORE_ATOMIC_BASE_PRIORITY_LEVEL). Without this config,
# if you use an IRQ with a priority of 0 or 1, irq_lock() and irq_unlock() have no effect
# over this IRQ.
