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 VDIP2. This is done by a combination of pulling up or pulling down the VNC1L
ACBUS5 (pin 46) and ACBUS6 (pin 47). The relevant portion of the VDIP2 module schematic is shown in
Figure 3.2 – VDIP2 On-Board Jumper Pin Configuration.
