Hi all. We just tried and all three bits can be used despite the fact datasheet proposes on page 37 that bit2 should be 0 and bit6 1 We tried to write 0x76 and subclients moved to 0x4e and 0x4f. Maybe the datasheet should be clearified that values on bit2 and bit6 are power on defaults but all three bits can be altered. Regards Rudolf
