Note that if you are using the MOD090-LP in UART mode, you may wish to include
a USB interface to SPI0 similar to that implemented in the Evaluation Board. This
would allow you to modify the conguration, to read back operating statistics and
to perform spectrum analysis. If those capabilities are not needed, then the cost
and space can be avoided.
