Refer to the DS280DF810 Programming Guide (SNLU182) for the complete register map and example programming sequences.
The DS280DF810 has a vendor ID register (0xFE), which will always read back 0x03. In addition, there are four device ID registers (0xEF, 0xF0, 0xF1, and 0xF3). Reading these five registers and confirming the expected value is a good way to verify SMBus communications between the SMBus Controller and the DS280DF810. In addition, writing a value to channel select Reg_0xFC and confirming the correct value is read back is a good way to verify SMBus write communications with the DS280DF810.
