Figure 4-4. MXIbus Termination
Configuration EEPROM
The VME-MXI-2 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 default user settings.
Use switches 1 and 2 of the four-position switch at location U21 to control
the operation of the EEPROM. The Restore Factory Configuration switch
(switch 1) causes the VME-MXI-2 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 VME-MXI-2 boots to an unusable state.
