3.3 I/O Configuration Using The Jumper Pin Header
Two three way jumper pin headers are provided to allow for simple configuration of the I/O on data and
control bus pins of the 48 pin QFN Vinculum-II. This is done by a combination of pulling up or pulling
down the 48 pin QFN Vinculum-II IOBUS25 (pin 46) and IOBUS26 (pin 47). The relevant portion of the
V2DIP2-48 module schematic is shown in
