 /*******************************************************************************
  * TRC_IRQ_PRIORITY_ORDER
  *
  * Macro which should be defined as an integer of 0 or 1.
  *
  * This should be 0 if lower IRQ priority values implies higher priority
  * levels, such as on ARM Cortex M. If the opposite scheme is used, i.e.,
  * if higher IRQ priority values means higher priority, this should be 1.
  *
  * This setting is not critical. It is used only to sort and colorize the
  * interrupts in priority order, in case you record interrupts using
  * the vTraceStoreISRBegin and vTraceStoreISREnd routines.
  *
  ******************************************************************************
  *
  * HWTC Macros
  *
  * These macros provides a hardware isolation layer representing the
  * hardware timer/counter used for the event timestamping.
  *
  * TRC_HWTC_COUNT: How to read the current value of the timer/counter.
  *
  * TRC_HWTC_TYPE: Tells the type of timer/counter used for TRC_HWTC_COUNT:
  *
  * - TRC_FREE_RUNNING_32BIT_INCR:
  *   Free-running 32-bit timer/counter, counting upwards from 0.
  *
  * - TRC_FREE_RUNNING_32BIT_DECR
  *   Free-running 32-bit timer/counter, counting downwards from 0xFFFFFFFF.
  *
  * - TRC_OS_TIMER_INCR
  *	 Periodic timer that drives the OS tick interrupt, counting upwards
  *   from 0 until (TRC_HWTC_PERIOD-1).
  *
  * - TRC_OS_TIMER_DECR
  *	 Periodic timer that drives the OS tick interrupt, counting downwards
  *   from TRC_HWTC_PERIOD-1 until 0.
  *
  * - TRC_CUSTOM_TIMER_INCR
  *   A custom timer or counter independent of the OS tick, counting
  *   downwards from TRC_HWTC_PERIOD-1 until 0. (Currently only supported
  *   in streaming mode).
  *
  * - TRC_CUSTOM_TIMER_DECR
  *   A custom timer independent of the OS tick, counting downwards
  *   from TRC_HWTC_PERIOD-1 until 0. (Currently only supported
  *   in streaming mode).
  *
  * TRC_HWTC_PERIOD: The number of HWTC_COUNT ticks until the timer wraps
  * around. If using TRC_FREE_RUNNING_32BIT_INCR/DECR, this should be 0.
  *
  * TRC_HWTC_FREQ_HZ: The clock rate of the TRC_HWTC_COUNT counter in Hz. If using
  * TRC_OS_TIMER_INCR/DECR, this is should be TRC_HWTC_PERIOD * TRACE_TICK_RATE_HZ.
  * If using a free-running timer, this is often TRACE_CPU_CLOCK_HZ (if running at
  * the core clock rate). If using TRC_CUSTOM_TIMER_INCR/DECR, this should match
  * the clock rate of your custom timer (i.e., TRC_HWTC_COUNT). If the default value
  * of TRC_HWTC_FREQ_HZ is incorrect for your setup, you can override it by calling
  * vTraceSetFrequency before calling vTraceEnable.
  *
  * TRC_HWTC_DIVISOR (used in snapshot mode only):
  * In snapshot mode, the timestamp resolution is TRC_HWTC_FREQ_HZ/TRC_HWTC_DIVISOR.
  * If the timer frequency is very high (hundreds of MHz), we recommend increasing
  * the TRC_HWTC_DIVISOR prescaler, to reduce the bandwidth needed to store
  * timestamps. This since extra "XTS" events are inserted if the time since the
  * previous event exceeds a certain limit (255 or 65535 depending on event type).
  * It is advised to keep the time between most events below 65535 native ticks
  * (after division by TRC_HWTC_DIVISOR) to avoid frequent XTS events.

	/*******************************************************************************
	* TRC_IRQ_PRIORITY_ORDER
	*
	* Macro which should be defined as an integer of 0 or 1.
	*
	* This should be 0 if lower IRQ priority values implies higher priority
	* levels, such as on ARM Cortex M. If the opposite scheme is used, i.e.,
	* if higher IRQ priority values means higher priority, this should be 1.
	*
	* This setting is not critical. It is used only to sort and colorize the
	* interrupts in priority order, in case you record interrupts using
	* the vTraceStoreISRBegin and vTraceStoreISREnd routines.
	*
	******************************************************************************
	*
	* HWTC Macros
	*
	* These macros provides a hardware isolation layer representing the
	* hardware timer/counter used for the event timestamping.
	*
	* TRC_HWTC_COUNT: How to read the current value of the timer/counter.
	*
	* TRC_HWTC_TYPE: Tells the type of timer/counter used for TRC_HWTC_COUNT:
	*
	* - TRC_FREE_RUNNING_32BIT_INCR:
	* Free-running 32-bit timer/counter, counting upwards from 0.
	*
	* - TRC_FREE_RUNNING_32BIT_DECR
	* Free-running 32-bit timer/counter, counting downwards from 0xFFFFFFFF.
	*
	* - TRC_OS_TIMER_INCR
	* Periodic timer that drives the OS tick interrupt, counting upwards
	* from 0 until (TRC_HWTC_PERIOD-1).
	*
	* - TRC_OS_TIMER_DECR
	* Periodic timer that drives the OS tick interrupt, counting downwards
	* from TRC_HWTC_PERIOD-1 until 0.
	*
	* - TRC_CUSTOM_TIMER_INCR
	* A custom timer or counter independent of the OS tick, counting
	* downwards from TRC_HWTC_PERIOD-1 until 0. (Currently only supported
	* in streaming mode).
	*
	* - TRC_CUSTOM_TIMER_DECR
	* A custom timer independent of the OS tick, counting downwards
	* from TRC_HWTC_PERIOD-1 until 0. (Currently only supported
	* in streaming mode).
	*
	* TRC_HWTC_PERIOD: The number of HWTC_COUNT ticks until the timer wraps
	* around. If using TRC_FREE_RUNNING_32BIT_INCR/DECR, this should be 0.
	*
	* TRC_HWTC_FREQ_HZ: The clock rate of the TRC_HWTC_COUNT counter in Hz. If using
	* TRC_OS_TIMER_INCR/DECR, this is should be TRC_HWTC_PERIOD * TRACE_TICK_RATE_HZ.
	* If using a free-running timer, this is often TRACE_CPU_CLOCK_HZ (if running at
	* the core clock rate). If using TRC_CUSTOM_TIMER_INCR/DECR, this should match
	* the clock rate of your custom timer (i.e., TRC_HWTC_COUNT). If the default value
	* of TRC_HWTC_FREQ_HZ is incorrect for your setup, you can override it by calling
	* vTraceSetFrequency before calling vTraceEnable.
	*
	* TRC_HWTC_DIVISOR (used in snapshot mode only):
	* In snapshot mode, the timestamp resolution is TRC_HWTC_FREQ_HZ/TRC_HWTC_DIVISOR.
	* If the timer frequency is very high (hundreds of MHz), we recommend increasing
	* the TRC_HWTC_DIVISOR prescaler, to reduce the bandwidth needed to store
	* timestamps. This since extra "XTS" events are inserted if the time since the
	* previous event exceeds a certain limit (255 or 65535 depending on event type).
	* It is advised to keep the time between most events below 65535 native ticks
	* (after division by TRC_HWTC_DIVISOR) to avoid frequent XTS events.
