long mpiMotorFlashConfigSet(MPIMotor       motor,
                            void           *flash,
                            MPIMotorConfig *config,
                            void           *external) 

MotorFlashConfigSet sets a Motor's (motor) flash configuration using data from the structure pointed to by config, and also using data from the implementation-specific structure pointed to by external (if external is not NULL).

The Motor's flash configuration information in external is in addition to the Motor's flash configuration information in config, i.e, the flash configuration information in config and in external is not the same information. Note that config or external can be NULL (but not both NULL).

external either points to a structure of type MEIMotorConfig{} or is NULL.
