Configuration Options
Systems using TetraHub must have an external EEPROM in order for the device to have a unique VID, PID, and DID. The
TetraHub can talk to SPI EEPROM that are double byte addressable only. TetraHub uses the command format from the '040
parts. The TetraHub cannot talk to ‘080 EEPROM parts, as the read command format used for talking to ‘080 is not the same as
‘040. The '010s and '020s uses the same command format as used to interface with the ‘040 and hence these can also be used
to interface with the TetraHub.
8.1
When used in default mode, only a unique VID, PID, and DID must be present in the external SPI EEPROM. The contents of the
EEPROM must contain this information in the following format:
Default – 0xD0 Load

Configured – 0xD2 Load
