Write to DF example: Assuming: data1 locates at address 0x4000 and data2 locates at address 0x4002. Both data1 and data2 are U2 type. To update data1 and data2, send an SMBus block write with command = 0x44 block = starting address + DF data block = 0x00 + 0x40 + data1_LowByte + data1_HighByte + data2_LowByte + data2_HighByte To read the DF, send an SMBus block write to the ManufacturerBlockAccess(), followed by the starting address, then send an SMBus block read to the ManufacturerBlockAccess(). The return data contains the starting address followed by 32 bytes of DF data in Little Endian. Read from DF example: Taking the same assuming from the read DF example, to read DF, a. Send SMBus write block with command 0x44, block = 0x00 + 0x40 b. Send SMBus read block with command 0x44 The returned block = a starting address + 32 bytes of DF data = 0x00 + 0x40 + data1_LowByte + data1_HighByte + data2_LowByte + data2_HighByte.... data32_LowByte + data32_HighByte
