Bused Resource Command
Bused Resource Status
If the IPMC receives a Bused Resource command from IPMB-0, it asserts an appropriate
event and notifies the payload which uses the Bused Resource Status command over the
SIPL. When the IPMC receives a Bused Resource Status command, the respective bit in the
IPMC status is cleared.

The payload must issue a Bused Resource Status command before the payload communica-
tion time-out time. If the payload does not issue such a command before the payload com-
munication time-out time, the IPMC sends the 0xC3 completion code (Time-Out) in the
