2.2.1

CC1/CC2

CC1 and CC2 are the configuration channel pins used for connection and attachment detection, plug orientation

determination, USB power delivery communication, and system configuration management across USB Type-C

cable. CC1 and CC2 are HiZ during reset.

2.2.2

CC1DB/CC2DB

CC1DB and CC2DB are used for dead battery mode. This mode is enabled by connecting CC1DB and CC2DB

respectively to CC1 and CC2. Thanks to this connection, the pull-down terminations on the CC pins are present

by default even if the device is not supplied (see Section 3.5 Dead battery mode).

Warning: CC1DB and CC2DB must be connected to ground when dead battery mode is not supported.
