1. Code Example Description:
----------------------------
This code example shows using a single SPI module in conjunction with a GPIO to generate an SPI communication that will work with most SPI Slave devices.

The code sends from 00h through FFh and then cycles through again.  A delay was added to permit catching the output on a logic analyzer easier.
