Note
In UART operation, the implemented protocol does not directly use the device address. An SSI ID
equal to the device address+1 is used. For example, the theoretical device address range of 0 to
127 corresponds to an SSI ID range of 1 to 128.
Device Address (I
2
C)
The I
2
C interface address can be set through device pins and the DevAddr register.
The upper 5 bits (on 24-pin device) or 6 bits (on 16-pin device) are set through the DevAddr register.
While the lower 2-bits (24-pin device) or 1-bit (16-pin device) are set through the Addr0 and ADDR1 pins,
according to the following figure.

Device Address (16-pin Package)
The DevAddr register bits 23 through 6 are not used and their status has no effect on the device address
configuration.
A change of the address is always effective after a power-on or reset. During the initialization following a
power-on or reset, the DevAddr register value is restored with the value contained in Flash memory and
the address pin status is acquired.
It is possible to modify the device address by setting the DevAddr register (through any of the interfaces)
as well as the address pins status. If DevAddr register is modified, it is necessary to save its content into
Flash through the ACC command. Following a reset or power-on the device will resume operation with
the new address.
