/*  The thread execution profile kit is designed to track thread execution time 
    based on the hardware timer defined by TX_EXECUTION_TIME_SOURCE and 
    TX_EXECUTION_MAX_TIME_SOURCE below. When the thread's total time reaches 
    the maximum value, it remains there until the time is reset to 0 via a call
    to tx_thread_execution_time_reset. There are several assumptions to the 
    operation of this kit, as follows:

    1.  The TX_EXECUTION_TIME_SOURCE and TX_EXECUTION_MAX_TIME_SOURCE macros are 
        defined to utilize a local hardware time source.

    2.  The following routines are called from assembly code:
            VOID  _tx_execution_thread_enter(void);
            VOID  _tx_execution_thread_exit(void);
            VOID  _tx_execution_isr_enter(void);
            VOID  _tx_execution_isr_exit(void);

    3.  The ThreadX library must be rebuilt with TX_EXECUTION_PROFILE_ENABLE so 
        the assembly code macros are enabled to call the execution profile routines.  

    4.  Add tx_execution_profile.c to the application build.  */
