/*******************************************************************************
 * 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.
