7.5.1.2 SMBUS/I2C Register Control Interface

If EN_SMB=L3 (SMBus / I2C control mode), the DS160PR410 is configured through a standard I2C or SMBus interface that may operate up to 400 kHz. The slave address of the DS160PR410 is determined by the pin strap settings on the EQ1_ADDR1 and EQ0_ADDR0 pins. The device can be configured for best signal integrity and power settings in the system using the I2C or SMBus interface. The sixteen possible slave addresses (8-bit) for the DS160PR410 are shown in Table 4.

Table 4. SMBUS/I2C Slave Address Settings

EQ1_ADDR1 EQ0_ADDR0 ADDRESS (DEC) ADDRESS (HEX)
L0 L0 48 30
L0 L1 50 32
L0 L2 52 34
L0 L3 54 36
L1 L0 56 38
L1 L1 58 3A
L1 L2 60 3C
L1 L3 62 3E
L2 L0 64 40
L2 L1 66 42
L2 L2 68 44
L2 L3 70 46
L3 L0 72 48
L3 L1 74 4A
L3 L2 76 4C
L3 L3 78 4E

The DS160PR410 can also be configured by reading from EEPROM. To enter into this mode SMB_EN must be set to L1. Refer to the Understanding EEPROM Programming for DS160PR410 PCI-Express Gen-4 Redriver application report (SNLA320) for details.
