1. The default configuration is in bold.
2. The UCPD DBn function is done by the port protection. The use of PB5 and PB14 to DBn function is only for development
purposes.

PB11 is used as I2C_SDA to interface the port protection and is
shared with MFX, touch panel, Ext_I2C, EEPROM, 3D accelerometer, 3D
gyroscope, camera, and STMod+.
UCPD_DBCC1 is connected to GND for UCPD DB function through the
STM32
MCU UCPD_DBCC1 is not connected to GND can be used for the
comparator or STMod+.
UCPD_DBCC2 is connected to GND for UCPD DB function through the
STM32.
MCU UCPD_DBCC2 is not connected to GND can be used for TSC
function.
