5.6 Trace Functions

5.6.1 Displaying the Trace Information

• The same hardware resource is used for acquisition of time stamps and the IRQ signals in the trace function.

Accordingly, the trace contents differ depending on the [Selection of the trace contents] setting in the [Trace

Acquisition Properties] dialog box.

Table 5.7 Trace Contents

Setting Description

When [Timestamp] is selected Acquires and displays timestamp in 32 bits. The IRQ signals

are not acquired.

When [IRQ7-0 all indications] is

selected

Acquires and displays the IRQ signals. The time stamp is

displayed with the lower 16 bits fixed to 0.

• When the user clock (system clock signal φ) has been selected for [Time measurement unit] in the [Trace

acquisition] dialog box, the time stamp is displayed for 32 bits in hexadecimal.

5.6.2 Specifying Trace Acquisition Conditions

• The trace will stop several cycles after a condition is satisfied.

• Six or more bus cycles are required between pass points of sequential trace stop conditions and reset

condition.

• Six or more bus cycles are required between the start and end of measurement when [1-2], [3-4], or [5-6] is

specified in [Run time count between trigger outputs] of the [Trace Acquisition Properties] dialog box.

• Fifteen or more bus cycles are required between the start and end of measurement when [7-8] is specified in

[Run time count between trigger outputs] of the [Trace Acquisition Properties] dialog box.

• Six or more bus cycles are required from the start of execution to satisfaction of a trace stop mode condition.

• A sequential break or a trace stop may be incorrect when the user program is executed after the specified

address condition has been applied as the PC address to start execution.

• The Point to Point trace mode is not available when channel 1 is used for the performance analysis function.

5.6.3 Searching for a Trace Record

• When the range for searching is specified in the [General] page, a PTR value to end the search can be

specified in the [Start PTR] option, and a PTR value to start the search can be specified in the [End PTR].

• When the user clock (i.e. system clock signal φ) has been selected in [Time measurement unit] of the [Trace

Acquisition Properties] dialog box, no time stamp information will be searched.

5.6.4 Filtering Trace Records

• After the trace information is filtered, all trace information displayed in the [Trace] window is saved; a range

for saving trace information cannot be specified. To save a specific range of trace information, the filter

range must be specified in the [General] page of the [Trace Filter] dialog box.

• When the user clock (i.e. system clock signal φ) has been selected in [Time measurement unit] of the [Trace

Acquisition Properties] dialog box, no time stamp information will be filtered.
