/*! \brief Clear a specific interrupt on the executing core
* \ingroup hardware_irq
*
* This method is only useful for "software" IRQs that are not connected to hardware (i.e. IRQs 26-31)
* as the the NVIC always reflects the current state of the IRQ state of the hardware for hardware IRQs, and clearing
* of the IRQ state of the hardware is performed via the hardware's registers instead.
