Configuration
PB11
SB49
ON
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+.
PB5
JP13
ON
UCPD_DBCC1 is connected to GND for UCPD DB function through the
STM32
OFF
MCU UCPD_DBCC1 is not connected to GND can be used for the
comparator or STMod+.
PB14
JP9
ON
UCPD_DBCC2 is connected to GND for UCPD DB function through the
STM32.
OFF
MCU UCPD_DBCC2 is not connected to GND can be used for TSC
function.
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.
