When BASEPRI is set to … WebPriority Level Cortex-M architecture defines up to 255 priority levels, with priority level zero being the highest (most urgent) priority. The actual number of priority levels (which must be a power of two) which an MCU supports is left to be decided by the silicon vendors. Priority level is encoded in one of the NVIC registers.
