Description

Definitions used by interrupt priority functions.

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.
