Host Computer's Software Connection (with I2C FPGA or other device) Available
Reference Design (Logic Architecture Layer = Reference Architecture Layer)
The I2C bus is used to deliver MicroBlaze API Commands (MB Commands) to FPGA's MicroBlaze through FPGA's XPS_I2C_SLAVE custom IP block. The I2C bus is also used to retrieve the status of the MicroBlaze (SET_INTERRUPT command, FX22MB_REG0_GETVERSION command, GET_INTERRUPT command). See Reference Architecture Layer.
