GoWAIT_CONNECTtoDIS

The LSI hardware automatically performs the processing necessary to switch from the
"WAIT_CONNECT" state to the "DISABLED" state when "GoWAIT_CONNECTtoDIS" is
set to host state change execute (H_NegoControl_0.AutoMode).
The procedures are given below. The LSI hardware performs steps (2) to (5) automatically.
(1) The firmware sets the host state change execute (H_NegoControl_0.AutoMode) to
(2) Performs the same processing performed for "GoWAIT_CONNECT" (T0).
(3) Detects connection and issues connect detection status notification
(4) Performs the same processing performed for "GoDISABLED" (T1).
(5) Issues disabled completion status (H_SIE_IntStat_1.DisabledCmp) (T2).
Note that the timing for each state is the same as when executing "GoWAIT_CONNECT"
and "GoDISABLED." For detailed information on timing, refer to "1.4.10.3.2
GoWAIT_CONNECT" and "1.4.10.3.3 GoDISABLED," respectively.
For detailed information on procedures and timing when an error (disconnection or VBUS
error) is detected in midcourse, refer to "1.4.10.2.2 Disconnect Detection" and "1.4.10.2.1
VBUS Error Detection."
