6.3 Functional pin connection

As the routing of the functional signals (Reset, UARTDn, CANn, NWIRE and FP4) between the device SMD pad
area and the Jumpers connecting the Electrical Area and Functional Area is based on the FK3 device, the routing
of those signals for other Fx3 devices must be place manually.
To do so, connect a wire between the device pin (e.g. from one of the through holes in the Pin Patch areas) and
the functional side of the related signal jumper.
Caution: Do not close the related Jumpers of any of the newly routed signals as this can lead to a direct
connection between different device pins.
Be aware that no further disconnection by the use of jumpers between the Electrical Area and
Functional Area is possible after wiring the signals for other than FK3 devices.

6.3.1 Jumper overview

The location of all jumpers located on the board can be seen in the Figure 6-9.
Pin 1 of each Jumper field is marked with a black square.
