ADC - DAC Communications Test Complete

Forces adcDataOutPackage  to high, and this shows through on the
dacDataIn correctly.
Removal of ADC-DAC Communications Test

Removes the hard programming of the adcDataOutPackage so that everything
should work.

Current problems: As far as I can tell the adcOut should be 4 bits don't
care, 8 bits data, and 4 bits of zero. However the final 4 bits are not
showing up as 0, which is confusing. They change between 0 and 1.
