that may require seconds to accumulate the first reading after a re-arm.
[4:0] – reserved. Ignore on read.
4 Current State Mask
[7] – 1b = FRU Operational State M7 - Communication Lost
[6] – 1b = FRU Operational State M6 - FRU Deactivation In Progress
[5] – 1b = FRU Operational State M5 - FRU Deactivation Request
[4] – 1b = FRU Operational State M4 - FRU Active
[3] – 1b = FRU Operational State M3 - FRU Activation in Progress
[2] – 1b = FRU Operational State M2 - FRU Activation Request
[1] – 1b = FRU Operational State M1 - FRU Inactive
[0] – 1b = FRU Operational State M0 - FRU Not Installed
(5) [7:0] – Optional/Reserved. If provided, write as 80h (IPMI restriction).

4.2.2 Get Sensor Reading (Physical IPMB-0 Sensor)
Byte Data field
Request data 1 Sensor Number (FFh = reserved)
1 Completion Code
2 [7] – IPMB B Override State
0b = Override state, bus isolated
1b = Local Control state - IPM Controller determines state of bus.
[6:4] = IPMB B Local Status
0h = No Failure. Bus enabled if no override in effect.
1h = Unable to drive clock HI
2h = Unable to drive data HI
3h = Unable to drive clock LO
4h = Unable to drive data LO
5h = Clock low timeout
6h = Under test (the IPM Controller is attempting to determine if it is
causing a bus hang).
7h = Undiagnosed Communications Failure
[3] – IPMB A Override State
0b = Override state, bus isolated
1b = Local Control state - IPM Controller determines state of bus.
[2:0] = IPMB A Local Status
0h = No failure. Bus enabled if no override in effect.
1h = Unable to drive clock HI
2h = Unable to drive data HI
3h = Unable to drive clock LO
4h = Unable to drive data LO
5h = Clock low timeout
6h = Under test (the IPM Controller is attempting to determine
if it is causing a bus hang).
7h = Undiagnosed Communications Failure
Response data
3 Standard IPMI byte (see “Get Sensor Reading” in IPMI specification)
[7] – 0b = All Event Messages disabled from this sensor
