Hello TI experts:
In the dlp4710evm-lc_sch reference schematic diagram, IIC1 of the DLPC3479 main chip is 1.8V, which is directly connected to IIC0 3.3V of the DLPC3479 slave chip.
Q1:Will this cause problems with the IIC1 pin of the main chip? For example, the voltage exceeds the standard (page 15 of the DLPC3479 manual, the maximum voltage of IIC1 is 1.96V).
Can it be connected like this?
Q2: Can I connect IIC1 of DLPC3479 main chip with IIC1 of DLPC3479 slave chip?
Or is there an error in the schematic or datasheet of DLPC3479?
