5.2 I/O Multiplexer Configuration
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.
The IOMux is fully integrated into the VNC2 IDE (Integrated development
Environment) which is available to download: Vinculum-II Toolchain. A screenshot of the IOMux utility is
shown in figure 5.5 below.
The IOMux utility user guide is available to download: VINCULUM-II IO_Mux Configuration Utility User
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:
Package 32pin (LQFP & QFN)- Twelve I/O pins – IOBUS0 to IOBUS11
Package 48pin (LQFP & QFN)- Twenty eight I/O pins – IOBUS0 to IOBUS27
Package 64pin (LQFP & QFN)- Forty-four I/O pins – IOBUS0 to IOBUS43
Section 3.12 shows the default signal settings for all three package sizes.
