XETK-S20.1

Defines the type of the microcontroller used in the ECU.

Defines the frequency used for the DAP interface.

Defines whether 1 data pin (DAP1 (2Pin-DAP)) or 2 data pins (DAP2 (3Pin-DAP)) are used. DAP2 supports a higher data rate than DAP1 via the DAP interface.

Selects how the XETK controls the ECU watchdog.

• Controlled by ECU: The XETK will not drive the signal.
• Enabled: Enables watchdog control from the XETK debugger connector. The XETK will drive the signal as configured to enable the watchdog when the debugger requests the watchdog to be enabled.
• Disabled: The XETK will drive the signal as configured to disable the watchdog.

Controls which level of the watchdog disable signal shall disable the watchdog.

• Low: Low level shall disable the watchdog.
• High: High Level shall disable the watchdog.

Defines the hardware handshake timeout in case the ECU did not perform or does not support a hardware handshake.

To force the ECU to perform the handshake, enter -1 (infinite).  Using this setting, measurement and calibration is only possible if the ECU performs the specified handshake type.

Otherwise enter a value between 0 and 65534 ms.  The value should be set to the earliest time the XETK should access the ECU memory after the ECU is running (both powered and out of reset).

Selects the method used for the hardware handshake between the ECU and the XETK, as well as for triggering a data acquisition by the ECU.

• Pinless Triggering: Integrated functionality of the debug interface is used for handshake and triggering. No additional microcontroller pins are required.

Selects the polling rate in μs. Typically at least twice as fast as the fastest raster in a measurement.

Selects the signal the ETK will use for ECU standby RAM (working page) power supply supervision.

• ETK Standby Supply: ETK is monitoring the standby supply it provides to the ECU.
• ECU Standby Supply: ETK is monitoring the ECU standby supply; the ECU is not using the standby supply from the ETK.
• No Standby Supply: ETK is monitoring the standard ECU power supply; the working page is not using a standby supply.

In case Enhanced Coldstart is used it defines the base address of the Distab Checksum array.

• 0xFFFFFFFF: Enhanced Coldstart is not used.
• Any other value: Enhanced Coldstart is used. The value is the base address of Distab Checksum array.

Defines how the XETK shall behave if an overload occurs during data processing.

• Drop Data and Continue Measurement: The XETK drops measurement data, sends an error event and continues measurement.
• Stop Measurement: The XETK stops the measurement and sends an error event.

Defines how the ETK will configure the microcontroller’s DAP timeout value. When the microcontroller’s internal bus is under high load, it takes additional time to read or write data using the DAP Interface. To reduce the chance of a DAP timeout, the ETK can be configured to increase the DAP timeout value.

• On / Auto – Detect: The ETK will increase the timeout, if supported by the microcontroller.

• Off – The ETK will leave the timeout at the default value defined by the microcontroller.
