JP2 - CLKI Selection
JP2 selects the source for CLKI.
When the jumper is at position 1-2, the CLKI source is provided by the oscillator at U3
(default setting).
When the jumper is at position 2-3, the CLKI source is the same as BUSCLK (provided by
the non-PCI host system).

JP3 - CoreVDD Current
JP3 allows the mesurement of S1D13504 CoreVDD current consumption.
When the jumper is at position 1-2, the evaluation board is operating normally (default
setting).
When no jumper is installed, CoreVDD current comsumption can be measured by
connecting an ampmeter to JP3.
