When FIFO_WR# goes low FIFO_TXE# flag will always go high. FIFO_TXE# goes low again only when
there is still space for data to be written in to the module.
3.7 Debugger Interface
The purpose of the debugger interface is to provide access to the VNC2 silicon/firmware debugger. The
debug interface can be accessed via the J2-10 pin on the DIL connector or, more easily, it can be
accessed by connecting a VNC2_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

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.

5.0V module supply pin. This pin can be used to
provide the 5.0V input to the V2DIP2-32 from the
debugger interface when the V2DIP2-32 is not
powered from the USB connector (VBUs) or the
DIL connector pins J1-1 and J3-6.
Not connected. Used to make sure that the debug
module is connected correctly.
