*
* When TRC_CFG_SNAPSHOT_MODE is TRC_SNAPSHOT_MODE_STOP_WHEN_FULL, the

* Macro which should be defined as either zero (0) or one (1).
* Default is 1.
*
* Tracealyzer groups the events into "instances" based on Instance Finish
* Events (IFEs), produced either by default rules or calls to the recorder
* functions vTraceInstanceFinishedNow and vTraceInstanceFinishedNext.
*
* If TRC_CFG_USE_IMPLICIT_IFE_RULES is one (1), the default IFE rules is
* used, resulting in a "typical" grouping of events into instances.
* If these rules don't give appropriate instances in your case, you can
* override the default rules using vTraceInstanceFinishedNow/Next for one
* or several tasks. The default IFE rules are then disabled for those tasks.
*
* If TRC_CFG_USE_IMPLICIT_IFE_RULES is zero (0), the implicit IFE rules are
* disabled globally. You must then call vTraceInstanceFinishedNow or
* vTraceInstanceFinishedNext to manually group the events into instances,
* otherwise the tasks will appear a single long instance.
*
* The default IFE rules count the following events as "instance finished":
* - Task delay, delay until
* - Task suspend
* - Blocking on "input" operations, i.e., when the task is waiting for the
* next a message/signal/event. But only if this event is blocking.
*
* For details, see trcSnapshotKernelPort.h and look for references to the
* macro trcKERNEL_HOOKS_SET_TASK_INSTANCE_FINISHED.

/******************************************************************************
* TRC_CFG_USE_16BIT_OBJECT_HANDLES
*
* Macro which should be defined as either zero (0) or one (1).
*
* If set to 0 (zero), the recorder uses 8-bit handles to identify kernel
* objects such as tasks and queues. This limits the supported number of
* concurrently active objects to 255 of each type (tasks, queues, mutexes,
* etc.) Note: 255, not 256, since handle 0 is reserved.
*
* If set to 1 (one), the recorder uses 16-bit handles to identify kernel
* objects such as tasks and queues. This limits the supported number of
* concurrent objects to 65535 of each type (object class). However, since the
* object property table is limited to 64 KB, the practical limit is about
* 3000 objects in total.
*
* Default is 0 (8-bit handles)
*
* NOTE: An object with handle above 255 will use an extra 4-byte record in
* the event buffer whenever the object is referenced. Moreover, some internal
* tables in the recorder gets slightly larger when using 16-bit handles.

*
* If this is one (1), the TRACE_ASSERT macro (used at various locations in the
* trace recorder) will verify that a relevant condition is true.
* If the condition is false, prvTraceError() will be called, which stops the
* recording and stores an error message that is displayed when opening the
* trace in Tracealyzer.
*
* This is used on several places in the recorder code for sanity checks on
* parameters. Can be switched off to reduce the footprint of the tracing, but

#define TRC_CFG_USE_TRACE_ASSERT 1
/*******************************************************************************
* TRC_CFG_USE_SEPARATE_USER_EVENT_BUFFER
*
* Macro which should be defined as an integer value.
*
* Set TRC_CFG_USE_SEPARATE_USER_EVENT_BUFFER to 1 to enable the
* separate user event buffer (UB).
* In this mode, user events are stored separately from other events,
* e.g., RTOS events. Thereby you can get a much longer history of
* user events as they don't need to share the buffer space with more
* frequent events.
*
* The UB is typically used with the snapshot ring-buffer mode, so the
* recording can continue when the main buffer gets full. And since the
* main buffer then overwrites the earliest events, Tracealyzer displays
* "Unknown Actor" instead of task scheduling for periods with UB data only.
*
* In UB mode, user events are structured as UB channels, which contains
* a channel name and a default format string. Register a UB channel using
* xTraceRegisterUBChannel.
*
* Events and data arguments are written using vTraceUBEvent and
* vTraceUBData. They are designed to provide efficient logging of
* repeating events, using the same format string within each channel.
*
* Examples:
*
* traceString chn1 = xTraceRegisterString("Channel 1");
* traceString fmt1 = xTraceRegisterString("Event!");
* traceUBChannel UBCh1 = xTraceRegisterUBChannel(chn1, fmt1);
*
* traceString chn2 = xTraceRegisterString("Channel 2");
* traceString fmt2 = xTraceRegisterString("X: %d, Y: %d");
* traceUBChannel UBCh2 = xTraceRegisterUBChannel(chn2, fmt2);
*
* // Result in "[Channel 1] Event!"
* vTraceUBEvent(UBCh1);
*
* // Result in "[Channel 2] X: 23, Y: 19"
* vTraceUBData(UBCh2, 23, 19);
*
* You can also use the other user event functions, like vTracePrintF.
* as they are then rerouted to the UB instead of the main event buffer.
* vTracePrintF then looks up the correct UB channel based on the
* provided channel name and format string, or creates a new UB channel
* if no match is found. The format string should therefore not contain
* "random" messages but mainly format specifiers. Random strings should
* be stored using %s and with the string as an argument.
*
* // Creates a new UB channel ("Channel 2", "%Z: %d")
* vTracePrintF(chn2, "%Z: %d", value1);
*
* // Finds the existing UB channel
* vTracePrintF(chn2, "%Z: %d", value2);

* If tracing multiple ISRs, this setting allows for accurate display of the

*
* vTraceStoreISREnd normally assumes that the ISR returns to the previous
