| Overview |
| ******** |
| |
| `TCPC <tcpc-specification>`_ (USB Type-C Port Controller) |
| The TCPC is a device used to simplify the implementation of a USB-C system |
| by providing the following three function: |
| |
| * VBUS and VCONN control `USB Type-C <usb-type-c-specification>`_: |
| The TCPC may provide a Source device, the mechanism to control VBUS sourcing, |
| and a Sink device, the mechanism to control VBUS sinking. A similar mechanism |
| is provided for the control of VCONN. |
| |
| * CC control and sensing: |
| The TCPC implements logic for controlling the CC pin pull-up and pull-down |
| resistors. It also provides a way to sense and report what resistors are |
| present on the CC pin. |
| |
| * Power Delivery message reception and transmission `USB Power Delivery <usb-pd-specification>`_: |
| The TCPC sends and receives messages constructed in the TCPM and places them |
| on the CC lines. |

| ======== |
| |
| The TCPC device driver functions as the liaison between the TCPC device and the |
| application software; this is accomplished by the Zephyr's API provided by the |
| device driver that's used to communicate with and control the TCPC device. |
