I design a board with four DS125BR820 units , these units use a external eeprom to load configuration data.
Following my design description:
tying four DS125BR820 devices to the same SDA and SCL bus.
Setting SMBus AD[3:0] of four devices to 0xB0,0xB2,0xB4, 0xB6
Daisy-chain READ_EN (Pin 26) and ALL_DONE (Pin 27) from one device to the next device in the sequence.
When i power on the board, the ALL_DONE (Pin 27) of the last device go to "0", it seems programming the four device is done correctly.
When start the sigcon software to access four DS125BR820 devices via I2C, it can only access the first unit's I2C interface with 0xB0 address.
Can anyone help to resolve the case
