+ * 0. This is default. If the RTC tick interrupt is masked for more than 1 tick by higher priority interrupts, then most likely
+ *    one or more RTC ticks are lost. The tick interrupt inside RTOS will detect this and make a correction needed. This is needed
+ *    for the RTOS internal timers to be more accurate.
+ * 1. The auto correction for RTOS tick is disabled even though few RTC tick interrupts were lost. This feature is desirable when debugging
+ *    the RTOS application and stepping though the code. After stepping when the application is continued in debug mode, the auto-corrections of
+ *    RTOS tick might cause asserts. Setting configUSE_DISABLE_TICK_AUTO_CORRECTION_DEBUG to 1 will make RTC and RTOS go out of sync but could be
+ *    convenient for debugging.
