/* RTOS ports that support interrupt nesting have the concept of a
* maximum system call (or maximum API call) interrupt priority.
* Interrupts that are above the maximum system call priority are keep
* permanently enabled, even when the RTOS kernel is in a critical section,
* but cannot make any calls to FreeRTOS API functions. If configASSERT()
* is defined in FreeRTOSConfig.h then
* portASSERT_IF_INTERRUPT_PRIORITY_INVALID() will result in an assertion
* failure if a FreeRTOS API function is called from an interrupt that has
* been assigned a priority above the configured maximum system call
* priority. Only FreeRTOS functions that end in FromISR can be called
* from interrupts that have been assigned a priority at or (logically)
* below the maximum system call interrupt priority. FreeRTOS maintains a
* separate interrupt safe API to ensure interrupt entry is as fast and as
* simple as possible. More information (albeit Cortex-M specific) is
* provided on the following link:
* https://www.FreeRTOS.org/RTOS-Cortex-M3-M4.html */
