10.8.2.2 Micro Level Messages — The following messages support the equipment-to-equipment micro level
handoff of material as defined in SEMI E32.
10.8.2.2.1 The messages which support the micro level are passed directly between the equipment. For the purpose
of the communication link, one of the equipment must be designated the host and the other the equipment. The
choice is up to the implementer. Equipment which are configurable to act as either host or equipment are suggested
for ease of installation.
10.8.2.2.2 The two equipment involved in a micro level transfer assume different roles. One equipment is
designated the “Primary Transfer Partner,” and the other is the “Secondary Transfer Partner” (see SEMI E32 for
more definition). While some consistency of roles is expected, this designation is fluid and may change from one
transfer to the next. The Primary Transfer Partner has more responsibility and thus initiates messages which the
Secondary does not.
10.8.2.2.3 The selection of “Host” and “Equipment” for the communication link is not related to the fluid
relationship of Primary and Secondary Transfer Partner. However, it is the designation of Primary or Secondary
which determines the originator of certain messages. It is for this reason that the designation P = Primary and S =
Secondary Transfer Partner.
