[TriEmbed] Using SPI

[Rodney Radford]

The two data lines MISO and MOSI can be in any state until the falling edge
of SCLK, so they could conceivably be used for other purposes.

In addition, if the only concern is programming the hex image (which is not
something you do while the motors are running), you could have some jumpers
that disconnect the SPI lines from the rest of the circuit while
downloading the image, and then put them back in place for normal operation.
