Bits 3:2 – CC2[1:0] CC2 State
If (TCPC_RCTL.CC2=Rp) or (ConnectResult=0):
| Value | Name | Description |
|---|---|---|
| 0 | CC2_SRC_OPEN | SRC.Open (Open, Rp) |
| 1 | CC2_SRC_RA | SRC.Ra (below maximum VRa) |
| 2 | CC2_SRC_RD | SRC.Rd (within the VRd range) |
| 3 | CC2_SRC_RESERVED | Reserved |
If (TCPC_RCTL.CC2 = Rd) or (ConnectResult=1):
| Value | Name | Description |
|---|---|---|
| 0 | CC2_SNK_OPEN | SNK.Open (Open, below maximum VRa) |
| 1 | CC2_SNK_DEFAULT | SRC.Default (above minimum VRd-Connect) |
| 2 | CC2_SNK_1P5A | SRC.Power1.5 (above minimum VRd-Connect) Detects Rp-1.5A |
| 3 | CC2_SNK_3A | SNK.Power3.0 (above minimum VRd-Connect) Detects Rp-3.0A |
If TCPC_RCTL.CC2=Ra, this field is set to 0.
If TCPC_RCTL.CC2=Open, this field is set to 0.
This field always returns 0 if (LK4CNX=1).
Otherwise, the returned value depends on TCPC_RCTL.CC2.

If TCPC_RCTL.CC1=Ra, this field is set to 0.
If TCPC_RCTL.CC1=Open, this field is set to 0.
This field always returns 0 if (LK4CNX=1).
Otherwise, the returned value depends on TCPC_RCTL.CC1.
