Bused Resource 
To send a Bused Resource command to the carrier controller, the payload uses the Bused 
Resource command of the SIPL.
Table 7-32:
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 
appropriate Bused Resource command reply.
