Linear EQ Configuration

Each of the TUSB546-DCI receiver lanes has individual controls for receiver equalization. The receiver equalization gain value can be controlled either through I2C registers or through GPIOs. Table 7-7 lists the gain value for each available combination when TUSB546-DCI is in GPIO mode. These same options are also available in I2C mode by updating registers DP0EQ_SEL, DP1EQ_SEL, DP2EQ_SEL, DP3EQ_SEL, EQ1_SEL, EQ2_SEL, and SSEQ_SEL.
