2.3I/OConfigurationUsingTheJumperPinHeader

TwothreewayjumperpinheadersareprovidedtoallowforsimpleconfigurationoftheI/Oondataandcontrolbus

pins of the VDIP2. This is done by a combination of pulling up or pulling down the VNC1L’s ACBUS5 (pin 46) and

ACBUS6(pin47).TherelevantportionoftheVDIP2moduleschematicisshowninfigure7,below.
