J1517x2 Header

Pin Mode (Default): EQ1 controls for each downstream device and device bank.

Use pins 1–8 for configuring EQ1 pin of DS1 device.

Use pins 9–16 for configuring EQ1 pin of DS2 device.

Use pins 17–24 for configuring EQ1 pin of DS3 device.

Use pins 25–32 for configuring EQ1 pin of DS4 device.

SMBus, I2C Modes: ADDR1 controls for each downstream device.

Use pins 1–8 for configuring ADDR1 pin of DS1 device.

Use pins 9–16 for configuring ADDR1 pin of DS2 device.

Use pins 17–24 for configuring ADDR1 pin of DS3 device.
