The following values are used by the interrupt priority functions.
The value of IRQ_PRIORITY_Msk specifies maximum interrupt priority value and can be used as parameter for the functions IRQ_GetPriority and IRQ_SetPriorityGroupBits to retrieve implementation specific priority values.
The value of IRQ_PRIORITY_ERROR is used by functions IRQ_GetPriority, IRQ_GetPriorityMask and IRQ_GetPriorityGroupBits to signal function execution error.
