I2C Read-back Failure Mode on Specific Use Scenario in MachXO2 and MachXO3 Products and Work-Around SolutionsLattice is issuing this Product Bulletin to inform that it identified a potential failure mode on I2C read-back under certain use case scenarios in MachXO2 and MachXO3 Devices. The failure mode is a limited use case, and most customers will not be impacted. However, for the limited set of customers using the device in the use modes described below, there is a risk in I2C read-back. We are communicating the potential failure modes and workaround solutions to address it.Known Issue:I2C Read-back Data is undefined in certain cases if the Embedded Function Block (EFB) WISHBONE clock input port (‘wb_clk_i’) is unconnected or is too slow.
