Load USER/FACTORY Configuration
The VXI-MIO module has an onboard EEPROM, which stores default
register values that are loaded at power-on. The EEPROM is divided
into two halves—a factory-configuration half, and a user-configuration
half. Both halves were factory configured with the same configuration
values so you can modify the user-configurable half, while the factory-
configured half stores a back-up of the factory settings.
Use switch S2 to control the operation of the EEPROM. The switch
causes the VXI-MIO module to boot off the factory-configured half
instead of the user-modified settings. This is useful in the event that the
user-configured half of the EEPROM becomes corrupted in such a way
that the VXI-MIO module boots to an unusable state. Refer to
Figure 2-5 for configuration settings.
