FPGA Configuration Function

The FPGA module performs FPGA configuration when:
 Upon power-on or remote reset
 At the time of FPGA download (configuration data file is JIC format, RPD format)
 At the time of FPGA download (configuration data file is SOF format)
For , configuration is performed using the configuration data saved in the configuration ROM inside the FPGA module.
For , configuration takes place using the data downloaded from the FPGA design software.
In addition, the FPGA module has FPGA parameters that change the operation of each block in the FPGA, and after
configuration is completed, the FPGA parameters saved in the nonvolatile memory are set to the FPGA register areas.

■Configuration data
Write from FPGA design software or FPGA Module Configuration Tool using the FPGA download function. ( Page 300
FPGA Download Function)
■FPGA parameter
FPGA parameters can be set from the FPGA Module Configuration Tool, the structure of which is described below.
• Parameters for register areas in the standard circuit part
• Parameters for user circuit part register areas
When writing to the FPGA module, if "Parameter write (Memory + Non-volatile memory)" is selected as the write destination,
the data will be saved in the non-volatile memory of the FPGA module and retained even after the power is turned off. For
details on the write operation, refer to the following.

In addition, FPGA parameters can be set from a program and written to non-volatile memory. For details on FPGA
parameters, refer to the following.
