The DS160PR810 internal registers can be accessed through standard SMBus protocol. The DS160PR810 features two banks of channels, Bank 0 (Channels 0–3) and Bank 1 (Channels 4–7), each featuring a separate register set and requiring a unique SMBus slave address. The SMBus slave address pairs (one for each channel bank) are determined at power up based on the configuration of the EQ0_0/ADDR1 and EQ1_0/ADDR0 pins. The pin state is read on power up, after the internal power-on reset signal is deasserted.

There are 16 unique SMBus slave address pairs (one address for each channel bank) that can be assigned to the device by placing external resistor straps on the EQ0_0/ADDR1 and EQ1_0/ADDR0 pins as shown in Table 2-3. When multiple DS160PR810 devices are on the same SMBus interface bus, each channel bank of each device must be configured with a unique SMBus slave address pair.
