9.2.2 Detailed Design Procedure
A typical usage of the TUSB564-DCI device is shown in Figure 28. The device can be controlled either through its GPIO pins or through its I2C interface. In the example shown below, a Type-C PD controller is used to configure the device through the I2C interface. When configured for I2C mode, pins 29 and 32 can be left unconnected if DCI is not used. In I2C mode, the equalization settings for each receiver can be independently controlled through I2C registers. For this reason, all of the equalization pins (EQ[1:0], SSEQ[1:0], and DPEQ[1:0]) can be left unconnected. If these pins are left unconnected, the TUSB546A-DCI 7-bit I2C slave address will be 0x12 because both DPEQ/A1 and SSEQ0/A0 will be at pin level "F". If a different I2C slave address is desired, DPEQ/A1 and SSEQ0/A0 pins should be set to a level which produces the desired I2C slave address.
