- * @details
- *  This module contains functions to safely disable and enable interrupts
- *  at CPU level. INT_Disable() disables interrupts globally and increments a lock
- *  level counter (counting semaphore). INT_Enable() decrements the lock level 
- *  counter and enable interrupts if the counter reaches zero.
- *
- *  These functions would normally be used to secure critical regions, and 
- *  to make sure that a critical section that calls into another critical 
- *  section does not unintentionally terminate the callee critical section.
- *
- *  These functions should also be used inside interrupt handlers:
- *  @verbatim
- *  void SysTick_Handler(void)
