The purpose of the debugger interface, J8, is to provide access to the VNC2 silicon/firmware debugger.
The debug interface can be accessed by connecting a VNC2_Debugger_Programmer_Module to the J8
connector. This debugger/programmer module will give access to the debugger through a USB connection
to a PC via the Integrated Development Environment (IDE). The IDE is accessed through a GUI to the
VNC2 software development tool-chain and gives the following debug capabilities through the debugger
interface:
The IDE may be downloaded from
The Debugger Interface, and how to use it, is further described in the following applications note:

Not connected. Used to make sure that the debug
module is connected correctly.
Module ground supply pin
Can be used by an external device to reset the
VNC2. This pin is also used in combination with
PROG# and the UART interface to program
firmware into the VNC2.

5.0V module supply pin. This pin can be used to
provide the 5.0V input to the Vinco from the
debugger interface when the Vinco is not powered
from the USB connector (VBUs) or the CN1
