ADT7470: Can I perform a temperature readback of ADT7470 while in automatic fan control mode?

Question Is it possible to perform a temperature readback of ADT7470 while in automatic fan control mode. It is not clear from the section “temperature readback by the host” on page 14 of datasheet if the recommended procedure given for radback of temperature is applicable in both manual and automatic mode or just in manual mode? Answer The Host can read back the temperature in automatic mode. However there is a 5ppm error rate in automatic mode due to a collision between read and write access to the temperature registers. Our workaround at the moment is to take 5 samples, remove maximum and minimum and average the remaining 3 in auto mode to receive an accurate answer.

Question I noticed the /SMBALT signal going active, the returning to idle repeatedly. Inspection of the status registers rendered zeros, suggesting there was not a condition to be reported. Answer This is included in the latest version of the datasheet. This is something we only noticed in the past year. See attached image, or table 43 in the datasheet.
