Gowait_Connecttoop; If Hs Device Is Connected - Epson S2R72V18 Technical Manual

1.4.10.3.9

GoWAIT_CONNECTtoOP

The LSI hardware automatically performs the processing necessary to switch from the
"WAIT_CONNECT" state to the "OPERATIONAL" state when
"GoWAIT_CONNECTtoOP" is set to host state change execute
(H_NegoControl_0.AutoMode).

If HS Device is Connected

Shown below are the procedures performed when an HS device is connected. The LSI
hardware performs steps (2) to (9) automatically.
(1) The firmware sets the host state change execute (H_NegoControl_0.AutoMode)
to "GoWAIT_CONNECTtoOP" (T0).
(2) Performs the same processing performed for "GoWAIT_CONNECT" (T0).
(3) Detects connection and issues connection detection status notification
(H_SIE_IntStat_0.DetectCon) (T1).
(4) Performs the same processing performed for "GoDISABLED" (T1).
(5) Issues disabled completion status (H_SIE_IntStat_1.DisabledCmp) (T2).
(6) Performs the same processing performed for "GoRESET" (T2).
(7) Detects the device chirp and issues device chirp normal detection status
notification (H_SIE_IntStat_0.DetectDevChirpOK) (T3).
(8) Issues reset completion status (H_SIE_IntStat_1.ResetCmp) (T4).
(9) Performs the same processing performed for "GoOPERATIONAL" (T4).
Note that the timing for each state is the same as when executing
"GoWAIT_CONNECT," "GoDISABLED," "GoRESET," or "GoOPERATIONAL."
For detailed information on timing, refer to "1.4.10.3.2 GoWAIT_CONNECT,"
"1.4.10.3.3 GoDISABLED," "1.4.10.3.4 GoRESET," and "1.4.10.3.5
GoOPERATIONAL," respectively.
For detailed information on procedures and timing when an error (disconnection,
VBUS error, or device chirp error) is detected in midcourse, refer to "1.4.10.2.2
Disconnect Detection" and "1.4.10.2.1 VBUS Error Detection."
