The Configure Table button in the Trace Data viewer allows you to perform two actions:
- Configure Time Unit - Lets you set CPU frequency and convert the clock cycles, displayed in the Timestamp column, into real time in milliseconds, microseconds, or nanoseconds. Click this button and select the Configure Time Unit option. To convert the clock cycles into milliseconds, microseconds, or nanoseconds, select the corresponding option.
The Set CPU Frequency option allows you to set the CPU frequency needed to convert the clock cycles into real time. Select this option to display the Set CPU Frequency dialog box. Set the new CPU frequency according to requirements.
Note: The Configure Time Unit option is available in all other viewers also, that is Critical Code Data , Timeline , Performance , and Call Tree . All the viewers share the same time and frequency that you set for a particular viewer. For example, if you set time in microseconds for Trace Data viewer, all other viewers will display time in microseconds. - Configure Time Format - Enables the Timestamp column of the Trace Data viewer for time formatting, Radix : Hexadecimal or Decimal and Value : Absolute or Delta. Time radix formatting is available only if time unit is set to Time in cycles . The default format of time is displayed in Decimal and Absolute value. Delta is calculated for same source event. The Delta value for a specific timestamp is the difference between current timestamp and previous timestamp with same source event as current one. If Delta value is negative, it will be displayed as zero.
Note: For HCS08 and ColdFire targets, the current value is a difference between current timestamp and the value from the previous row trace. For Kinetis (ITM and ETM source events), the difference is made with timestamp from the previous row only if it has the same source event as current, otherwise the difference is made with the previous timestamp that has the same source event as current.
