... System Power The TWR-MCF51MM can be powered by the Open Source BDM (OSBDM) circuit via the Mini-B USB connector when stand-alone. When assembled with the Tower System and the TWR-SER is configured to run USB device mode (J16 pin 3 and 4 connected), the Mini-B USB connector is no longer used as a power source and only used for OSBDM debugging purposes ...

... RS232 Interface An RS232 transceiver on the TWR-MCF51MM connects to a standard 2x5 pin header (refer to Figure 2). Selection jumpers J15 and J16 allow MCF51MM256 SCI2 signals to be routed to either the RS232 transceiver or the OSBDM circuit. Refer to Figure 5 for more details. Alternatively, when assembled as a Tower System, the MCF51MM256 SCI1 TX and RX are routed to the SER-TWR ...

... The TWR-MCF51MM features two expansion card-edge connectors that interface to elevator boards in a Tower System: the Primary and Secondary Elevator connectors. The Primary Elevator connector, comprised of sides A and B, is utilized by the TWR-MCF51MM, while the Secondary Elevator connector only makes connections to ground (GND). Figure 4 provides the pinout for the Primary Elevator connector. An “ ...

... MCF51MM256 for mass erase and programming via its USB interface. This on-chip bootloader does not consume user flash space. To enable USB bootloader mode for MCF51MM256, on the TWR-MCF51MM module, set SW3 DIP switch 2 and 3 to position 3, as indicated in Figure 7. NOTE: Under normal development you will need to set SW3 DIP switch 2 and 3 to position 2 ...
