Question:
On the MAX4814EEVKIT, how do I control the MAX3845 via the MAX4814 through I2C? The MAX4814EEVKIT datasheet (doc number 19-4048; Rev 0; 2/08), Table 1, page 4 shows jumper JU3 can be set to allow I2C control of the MAX3545 through the MAX4814E.
Answer:
Although originally planned, the option to control the MAX3845 via the MAX4814E was not implemented in the evaluation kit design. Thus, the evkit hardware is not designed to allow I2C mode of operation (controlling IN_SELx pins with the DOx pins via the MAX4814 register 1).
