I2C Pin Mapping Overview
Each I2C port can be routed to multiple alternative GPIO pin packs to suit your board layout: [1]
I2C1: SCL on PB6 (or PB8), SDA on PB7 (or PB9)
I2C2: SCL on PB10, SDA on PB11
I2C3: SCL on PA8 (or PH7), SDA on PC9 (or PH8) [1, 2]

FT2232 / FT2232H JTAG Pin Out Mapping Table
When configuring the FT2232 for JTAG debugging (typically using the MPSSE engine), Channel A (ADBUS) is used as the standard interface.
