FPGA Configuration
There are two ways to configure the FPGA:
1. Use the on-board JTAG header and Xilinx JTAG programming tools.
2. Send the configuration bitstream down the comport selected by SW1. The
Sundance library for the SMT351 includes a function to configure the FPGA in
this way.
The table below gives the possible settings for SW1:
