Table 5. Device Interface Field

Function Interface Field (1-byte)

This field provides a mechanism for a device to pass higher-layer SST device-specific information.

Value = 0x00

Device Interface Extension Field (1-byte)

This field is used to provide additional information about the device to the upper layers of software.

Value = 0x00

Reserved Field (3-bytes)

Value = 0x00 0x00 0x00

Vendor Specific ID Field (1-byte)

This field is set by the vendor in a way that uniquely identifies this device apart from all others with an otherwise common DIB

content.

Value = 0x00 – For Fixed address devices this field may be set to zero.

Client Device Address (1-byte)

SST Client Device Address is set according to the connection of the ADD0 pin. The combination part appears to software as two

sensors, a simple temperature and a simple voltage sensor residing at the same address. Float is defined as an unconnected pin.
