MFR_SPECIFIC_18: AVG_BLOCK_READ (E2h)

The AVG_BLOCK_READ command concatenates the DIAGNOSTIC_WORD with input and output average

telemetry information (IIN, VOUT, VIN, PIN) as well as temperature to capture all of the operating information of

the part in a single PMBus transaction. The block is 12 bytes long with telemetry information being sent out in the

same manner as if an individual READ_AVG_XXX command had been issued (shown below).

AVG_BLOCK_READ also specifies that the VIN, VOUT, and IIN measurements are all time-aligned whereas

there is a chance they may not be if read with individual PMBus commands. To read data from the

AVG_BLOCK_READ command, use the SMBus Block Read protocol.
