The initialization of the device for operation of the scheduler and tasks is handled within the main application source code file, task_scheduler.c. The call to SYSCFG_DL_init configures the hardware peripherals needed in the example code, then interrupts are enabled, and the TIMER_0_INST counter is started. After that, the code enters the scheduler loop.

Within the required IRQ handlers, the appropriate flags are set during interrupt to tell the scheduler a task is pending.
