2.2 Pin description 2.2.1 CC1 / CC2
CC1 and CC2 are the configuration channel pins used for connection and attachment detection, plug orientation determination. CC1 and CC2 are HiZ during reset.
2.2.2 CC1DB / CC2DB
CC1DB and CC2DB are enabled by dead battery mode 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 3.3 Dead battery mode). Warning: CC1DB and CC2DB must be connected to ground when dead battery mode is not supported, then Vsys must be used.
2.2.3 RESET
Active high reset.
2.2.4 I²C interface pins Table 3. I2C interface pin list Name Description
SCL I²C clock, need external pull-up SDA I²C data, need external pull-up ALERT I²C interrupt, need external pull-up ADDR0, ADDR1 I²C device address bits (see Section 4 I²C Interface) Warning: ADDR0 and ADDR1 pins must be connected to ground when there is no connection to an MCU.
