R/W/C

Size (Bits)

CC Status Description (Note 31)

7:6

Reserved

Reserved: 00b

LOOK4CON

0b: the FUSB307B is not looking for connection or indicated a

potential connection has been found when transitioned from a 1 to 0

1b: the FUSB307B looking for connection

CON_RES

0b: the FUSB307B is presenting Rp

1b: the FUSB307B is presenting Rd

This bit is only valid if the FUSB307B was a DRP and has stopped

DRP toggling

3:2

CC2_STAT

If (ROLE_CONTROL.CC2 = Rp) or (CON_RES = 0)

00b: SRC.Open (Open, Rp)

01b: SRC.Ra (below maximum vRa)

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

11b: reserved

If (ROLE_CONTROL.CC2 = Rd) or (CON_RES = 1)

00b: SNK.Open (Below maximum vRa)

01b: SNK.Default (Above minimum vRd−Connect)

10b: SNK.Power1.5 (Above minimum vRd−Connect)

Detects Rp 1.5 A

11b: SNK.Power3.0 (Above minimum vRd−Connect)

Detects Rp 3.0 A

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 (LOOK4CON = 1) or

(PWRCTRL.EN_VCONN = 1 and

TCPC_CONTROL.PlugOrientation = 0). Otherwise, the returned

value depends upon ROLE_CONTROL.CC2.

1:0

CC1_STAT

If (ROLE_CONTROL.CC1 = Rp) or (CON_RES = 0)

00b: SRC.Open (Open, Rp)

01b: SRC.Ra (below maximum vRa)

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

11b: reserved

If (ROLE_CONTROL.CC1 = Rd) or CON_RES = 1)

00b: SNK.Open (Below maximum vRa)

01b: SNK.Default (Above minimum vRd−Connect)

10b: SNK.Power1.5 (Above minimum vRd−Connect)

Detects Rp−1.5 A

11b: SNK.Power3.0 (Above minimum vRd−Connect)

Detects Rp−3.0 A

If ROLE_CONTROL.CC1 = Ra, this field is set to 00b

If ROLE_CONTROL.CC1 = Open, this field is set to 00b

This field always returns 00b if (LOOK4CON = 1) or

(PWRCTRL.EN_VCONN = 1 and

TCPC_CONTROL.PlugOrientation = 0). Otherwise, the returned

value depends upon ROLE_CONTROL.CC1.

31. An event change on this register cause an ALERTL.I_CCSTAT Interrupt.
