3.4.3 If no Daemon is Announced as Present
If no command call announces that a daemon is present, the MMC automatically uses the de-
fault timeout time 0 (endless wait) during the Hot Swap process. But if the timeout time was set
to a value 1…255 this time will be used in any case while waiting for the sleep state (signal).
Settings changed with this command are volatile (in particular quiesce timeout and OS daemon
present). Bits [6:5] are always settable, but once the quiesce request comes they cannot be
cleared until quiescence state is entered and exited.

REQUEST DATA
Byte Data Field
1 Control bits:
[7] - 1b = set quiesce wait timeout
[6] - 1b = quiescence acknowledge (OS ready)
[5] - 1b = OS daemon present
[4:0] Reserved
2 Quiesce wait timeout [sec]
a) An OS daemon is present (refer to bits above):
This is the maximum time from the moment on that the MMC receives FRU Control
(Quiesce) request until it sends back the appropriate Module Hot Swap event message.
b) No OS daemon is present (refer to bits above):
This is the maximum time from the moment on that the MMC receives FRU Control
(Quiesce) request until it sends back the appropriate Module Hot Swap event message. If
sleep state is recognized before timeout then the Module Hot Swap event message will be
sent immediately. If the time is set to 0 (default after reset) then the Module Hot Swap
event message will only be sent after recognition of sleep state (signal).
