Table 10. Cn2 Motor-Control Terminal And Function Assignment - ST STM32G474E-EVAL User Manual

UM2514
If the STM32G474E-EVAL board is used, some PCB reworks are needed for motor control
applications: the goal is to disconnect peripherals sharing I/Os with motor control
connectors and connect these I/Os to motor control connectors.
