Device Info
The Device Info byte gives details regarding the PECI client configuration. At a
minimum, all clients supporting GetDIB will return the number of domains inside the
package using this field. With any client, at least one domain (Domain 0) must exist.
Therefore, the Number of Domains reported is defined as the number of domains in
addition to Domain 0. For example, if bit 2 of the Device Info byte returns a '1', that
would indicate that the PECI client supports two domains.
