 Function DIP Switch
     Used to configure function of GPIO12 to GPIO15 pins that are shared between devices, primarily between **JTAG Header** and **MicroSD Card**. By default, the **MicroSD Card** is enabled with all switches in *OFF* position. To enable the **JTAG Header** instead, switches in positions 3, 4, 5 and 6 should be put *ON*. If **JTAG** is not used and **MicroSD Card** is operated in the one-line mode, then GPIO12 and GPIO13 may be assigned to other functions. Please refer to `ESP32 LyraT V4.2 schematic`_ for more details.
 JTAG Header
-    Provides access to the **JTAG** interface of **ESP32-WROVER Module**. It may be used for debugging, application upload, as well as implementing several other functions, e.g., `Application Level Tracing <http://esp-idf.readthedocs.io/en/latest/api-reference/system/app_trace.html>`_. See :ref:`get-started-esp32-lyrat-v4.2-jtag-header` for pinout details. Before using **JTAG** signals to the header, **Function DIP Switch** should be enabled. Please note that when **JTAG** is in operation, **MicroSD Card** cannot be used and should be disconnected because some of JTAG signals are shared by both devices.
