Question
What are the minimum and maximum number of priority levelssupported by Cortex-M3/M4 based processor?
Solution
The ARM Cortex-M3/M4 processors support a priority level range from 0 to 255. However, the number of distinct priority levels is implementation defined and may be as few as 8. The priority level 0 is the highest and 255 is the lowest. The actual number of priority levels supported is determined by the number of priority bits implemented.
