Device Address Configuration
The SSI protocol utilizes 8-bit addressing for multipoint communications. The usable SSI ID range is 1 to
255. In multipoint systems with more than 4 targets, the user must configure device address bits in the
DEVADDR according to the formula SSI ID = Device Address +1 and save the values to Flash memory
as the default.
A change in the device address takes effect following a power-on or reset. During the initialization, the
DEVADDR register value is restored from Flash memory and the state of the address pins are acquired.
A device address of 'FF' is not supported. DEVADDR [23:6] bits are not used and have no effect on the
device address.
