Description

USB TYPE-C CONNECTOR INTERFACE

CC1/CC2

I/O

Type-C connector Configuration Channel (CC) pins. Initially used to determine when an attach has

occurred and what the orientation of the insertion is. Functionality after attach depends on mode of

operation detected.

Operating as a host:

1.

Sets the allowable charging current for VBUS to be sensed by the attached device

2.

Used to communicate with devices using USB BMC Power Delivery

3.

Used to detect when a detach has occurred

Operating as a device:

1.

Indicates what the allowable sink current is from the attached host. Used to communicate with

devices using USB BMC Power Delivery
