J15 17x2 Header
Pin Mode: EQ1 controls for each downstream device and device bank.
Use pins 1–8 for configuring EQ1_0 pin of Bank 0 of DS1 device.
Use pins 9–16 for configuring EQ1_1 pin of Bank 1 of DS1 device.
Use pins 17–24 for configuring EQ1_0 pin of Bank 0 of DS2 device.
Use pins 25–32 for configuring EQ1_1 pin of Bank 1 of DS2 device.
SMBus, I2C Modes: ADDR1 controls for each downstream device.
Use pins 1–8 for configuring ADDR1 pin of DS1 device.
Use pins 17–24 for configuring ADDR1 pin of DS2 device.
Install a shunt to achieve L0, L1, L2 or L3 level on the pin. Leave floating to
achieve L4 level on the pin.

Pin Mode: EQ0 controls for each downstream device and device bank.
Use pins 1–8 for configuring EQ0_0 pin of Bank 0 of DS1 device.
Use pins 9–16 for configuring EQ0_1 pin of Bank 1 of DS1 device.
Use pins 17–24 for configuring EQ0_0 pin of Bank 0 of DS2 device.
Use pins 25–32 for configuring EQ0_1 pin of Bank 1 of DS2 device.
SMBus, I2C Modes: ADDR0 controls for each downstream device.
Use pins 1–8 for configuring ADDR0 pin of DS1 device.
Use pins 17–24 for configuring ADDR0 pin of DS2 device.
Install a shunt to achieve L0, L1, L2 or L3 level on the pin. Leave floating to
achieve L4 level on the pin.
