5.2
The VNC2 I/O Multiplexer allows signals to be routed to different pins on the device. To simplify the
routing of signals, the VNC2 RTOS provides an utility (IOMux) to configure the I/O Multiplexer as the
designer requires.
Environment) which is available to download:

Guide
The following tables provide a lookup guide to determine what signals are available and the list of pins
that can be used:
Each VNC2 has a default state of IOBUS signals following a hard reset. The number of I/O pins available
are determined by the package size:
Section 3.12 shows the default signal settings for all three package sizes.
