Jumper
Figure 7 Interface Pins Layout
To connect the Pro-FLEX module pins to their development board periphery circuits the
respective pins need to be jumpered together. To isolate the Pro-FLEX module, remove
the jumpers. The jumper pins can be used to connect the Pro-FLEX module to an
application circuit and/or test/debug equipment, such as a multi-meter or oscilloscope.
In order to program or debug the Pro-FLEX module, the jumpers bridging
module pins 9 through 14 will need to be in place.
Additional details regarding Pro-FLEX module pin configurations can be found in the
Pro-FLEX datasheet.
