+ * that the application has correctly installed FreeRTOS interrupt handlers.
+ *
+ * An application can install FreeRTOS interrupt handlers in one of the following ways:
+ *   1. Direct Routing  -  Install the functions vPortSVCHandler and xPortPendSVHandler
+ *                         for SVC call and PendSV interrupts respectively.
+ *   2. Indirect Routing - Install separate handlers for SVC call and PendSV
+ *                         interrupts and route program control from those handlers
+ *                         to vPortSVCHandler and xPortPendSVHandler functions.
+ * The applications that use Indirect Routing must set configCHECK_HANDLER_INSTALLATION to 0.
+ *
+ * Defaults to 1 if left undefined. */
