Configuration EEPROM

The VXI-8340 series has an onboard EEPROM, which stores 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 values. You can modify
the user-configurable half, while the factory-configured half stores a
back-up of the default settings.

The Load Factory switch (switch S1) causes the VXI-8340 series 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-8340 series powers up in an unusable
state.

Figure C-3 shows the configuration settings for EEPROM operation.

EEPROM Operation

VXIbus CLK10 Routing

When the VXI-8340 series controller is installed in Slot 0 of your VXI
mainframe, it must drive the VXIbus CLK10 signal. You can drive this
signal from one of two sources: an onboard 10 MHz oscillator or an
external TTL clock generator attached to the front panel EXT CLK
connector. The CLK10 source is determined by the position of hardware
switch S2.
