JP1 - CLKI Source
JP1 selects the source for the CLKI input pin.
When the jumper is at position 1-2, the CLKI source is VCLKOUT from the Cypress clock
synthesizer (default setting).
When the jumper is at position 2-3, the CLKI source is the external oscillator at U6.
When no jumper is installed, the CLKI source is the BUSCLK signal from Header H5.

JP2 - CLKI2 Source
JP2 selects the source for the CLKI2 input pin.
When the jumper is at position 1-2, the CLKI2 source is MCLKOUT from the Cypress
clock synthesizer (default setting).
When the jumper is at position 2-3, the CLKI2 source is the external oscillator at U7.
