 * and will nest.
 *
 * Interrupts that are assigned a priority above
 * configMAX_API_CALL_INTERRUPT_PRIORITY cannot call any FreeRTOS API functions,
 * will nest, and will not be masked by FreeRTOS critical sections (although all
 * interrupts are briefly masked by the hardware itself on interrupt entry).
 *
 * FreeRTOS functions that can be called from an interrupt are those that end in
 * "FromISR".  FreeRTOS maintains a separate interrupt safe API to enable
 * interrupt entry to be shorter, faster, simpler and smaller.
 *
 * User definable interrupt priorities range from 2 (the lowest) to 15 (the

 *
 *	This is the simplest of the two methods but incurs a slightly longer
 * 	interrupt entry time.
 *
 *	2) By using an assembly stub that wraps the handler in the FreeRTOS
 *	portFREERTOS_INTERRUPT_ENTRY and portFREERTOS_INTERRUPT_EXIT macros.  The handler is installed
 *	using xPortInstallInterruptHandler().
 *
 * This method can always be used.  It is slightly more complex than
 * method 1 but benefits from a faster interrupt entry time.
