3.9 Debugger Interface
The purpose of the debugger interface is to provide access to the VNC2 silicon/firmware debugger. The
debug interface can be accessed by connecting a debug module to the J3 connector. This debug module
will give access to the debugger through a USB connection to a PC via the Integrated Development
Environment (IDE). The IDE is a graphical interface to the VNC2 software development tool-chain and
gives the following debug capabilities through the debugger interface:
The Debugger Interface, and how to use it, is further described in the following applications Note

V2DIP1-48 VNC2-48 Development Module Datasheet Version 1.0
Can be used by an external device to reset
the VNCL2. This pin is also used in
combination with PROG# and the UART
interface to program firmware into the
VNC2.
This pin is used in combination with the
RESET# pin and the UART interface to
program firmware into the VNC2.
Not connected. Used to make sure that the
5.0V module supply pin. This pin can be
used to provide the 5.0V input to the
V2DIP1-48 when the V2DIP1-48 is not
powered from the USB connector (VBUS)
or the debugger interface. Also connected
to DIL connector pins J1-2, J1-3 and J1-9
and J3-6.
debug module is connected correctly.
