8.2.1.1 Using the V2-EVAL Terminal ‘Spy’ Mode
The V2-EVAL hardware and terminal utility supports a „Spy‟ mode enabling the V2-EVAL terminal utility to
display data from the VNC2 UART RXD pin, when the VNC2 is communicating with an external UART
device. The following section outlines the steps to connect an external UART device to the VNC2 interface
and enabling the „Spy‟ mode.

Figure 8.3: Example IOMUX configuration code
1. The first step is to connect an external UART device to the VNC2 UART interface on the V2-EVAL
2. The next step is to configure the IOMUX configuration settings on the VNC2 device to check that
3. With the VNC2 device now programmed for UART operation, the next stage is to configure the
board. An external device can be connected to the board via I/O connectors CN3 – CN11 or via
the IOBUS connections in prototyping area P1.
the UART connections reflect the physical I/O pins being used on the V2-EVAL hardware. The
IOMUX settings are set within the VNC2 software code. A code example showing how to configure
the VNC2 IOMUX settings is shown in Figure 8.3.
The IOMUX configuration code can also be automatically generated using the Vinculum IOMUX
configuration utility, which is available as part of the Vinculum II development tools.
The IOMUX settings are incorporated into the VNC2 firmware file as part of the VNC2 software
development process. The settings are applied to the VNC2 when the firmware image is
downloaded to the VNC2 device.
V2-EVAL terminal utility for „Spy‟ mode. Open the utility and connect to the board. In the „Board
Control‟ panel select the „Spy‟ button. The step will reconfigure the onboard multiplexer. After
changing to „Spy‟ mode disconnect the terminal connection.
