=20 I am using a Benchmarq 2040 Gas Gauge, but this question relates to any = SMBus device, I think. =20 The following refers to Status register (0x16), Error Codes. If I Write to the Smart Battery then test for any error codes, they are = all clear. After a Read from the 2040, then test for any error codes, the code = returned is 0007 (Unknown error). Is this correct, or should it return = OK (no errors) ? I have looked all over the web and cannot find an answer.
