TI-RTOS例程问题，例程中有创建任务函数，但main函数不见在哪调用了

下面是官方TI-RTOS中LCD例程，main函数如下所示，例程中有创建任务函数Void lcdLowPriorityFxn(UArg a0, UArg a1) { }；但是main函数却不见在哪调用了，本人初学CC1310，搞不懂这个例程，请大神帮忙解答一下，谢谢啦！

/*
* ======== main ========
*
*/
int main(void)
{
/* Call board init functions */
Board_initGeneral();

/* Set constraints for standby, powerdown and idle mode */
Power_setConstraint(Power_IDLE_PD_DISALLOW);
Power_setConstraint(Power_SB_DISALLOW);
Power_setConstraint(Power_SD_DISALLOW);

System_printf("Starting the LCD example\nSystem provider is set to SysMin."
" Halt the target to view any SysMin contents in ROV.\n");
/* SysMin will only print to the console when you call flush or exit */
System_flush();

/* Start BIOS */
BIOS_start();

return (0);
}

求教啊
