PRODUCTION DATA.
When using the latest generation of FPD-Link III devices, the DS90UB949A-Q1 or DS90UB940-Q1/DS90UB948-Q1 registers may be accessed simultaneously from both local and remote I2C masters. These devices have internal logic to properly arbitrate between sources to allow proper read and write access without risk of corruption.
Access to remote I2C slaves would still be allowed in only one direction at a time.
