STATUS

If (ROLE_CONTROL.CC2 = Rp) or

(DrpResult = 0)

00b : SRC.Open (Open, Rp) (default)

01b : SRC.Ra (below maximum vRa)

10b : SRC.Rd (within the vRd range)

11b : reserved

If (ROLE_CONTROL.CC2 = Rd) or

(DrpResult = 1)

00b: SNK.Open (Below maximum vRa)

(default)

01b: SNK.Default (Above minimum

vRd-Connect)

10b: SNK.Power1.5 (Above minimum

vRd-Connect) Detects Rp 1.5A

11b: SNK.Power3.0 (Above minimum

vRd-Connect) Detects Rp 3.0A

If ROLE_CONTROL.CC2 = Ra, this

field is set to 00b

If ROLE_CONTROL.CC2 = Open, this

field is set to 00b

This field always returns 00b if

(DrpStatus = 1) or

(POWER_CONTROL.EnableVCONN =

1 and

POWER_CONTROL.PlugOrientation =

0). Otherwise, the returned value

depends upon ROLE_CONTROL.CC2.
