USB Type-C Port Controller (TCPC) |

################################# |

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. |

TCPC API |
|
======== |
|
|
|
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. |
