    7. The User can configure the interrupt priority of the OSTM Timer using `configTIMER_INT_PRIORITY`, with 16 levels available (0 being the highest priority and 15 the lowest).
    8. This port also supports the configuration of contiguous CPU cores in FreeRTOS, allowing the user to set task affinity for execution on specific cores or subsets of cores.
