FPGA DEVELOPMENT
A sample circuit is written in the configuration ROM of the factory-shipped FPGA module. This chapter shows an example of
changing the sample circuit.

FPGA Development Procedures

The only block that requires to be developed (design/verification) is the user circuit block (uc2_top.v). Do not modify the circuit
description of the standard circuit. If the standard circuit is modified, the operation of various functions cannot be guaranteed.
The FPGA configuration of the FPGA module is shown below.
