SPI Interface with TetraHub

Last Updated: June 15, 2011

Can a processor with a SPI interface be used to program the TetraHub?


No. The TetraHub is a fixed function device and is the master. It can talk to an external EEPROM using certain protocols as specified in the SPI EEPROM datasheet. Note that during reset the SPI lines are in a driven state and cannot be driven by any external processor and hence cannot be used to program the TetraHub.
