The assembled Tower System now has
three USB connectors:
1. The USB connector on TWR-SER
2. The USB connector on TWR-
3. The USB connector on the Primary
To power on an assembled Tower
System, connect the PC to mini-USB
port (J14) on the TWR-SER module. The
MCF51MM256 is programmed with a
blinking LED application, so you should
see LED 1 to LED 3 blink the first time
the board is powered. LED 1 to LED 3 are
located near the potentiometer. When set
up as an assembled Tower System, the
power source is from the TWR-SER mini-

MCF51MM is used for programming
and debugging the MCF51MM256
MCU. The debugger interface is the
Freescale open-source background
debug module (OSBDM).
elevator merely powers the Tower
System. There is no data through this
connector and is not used in this kit.

Connect the Tower
System to the Computer
USB. The TWR-MCF51MM mini-USB acts
only as an OSBDM function and should
not be used to power the system. Be sure
to connect TWR-SER USB before the
TWR-MCF51MM USB. Do not connect
TWR-MCF51MM USB without TWR-SER
USB or damage could be caused.
NOTE: When the TWR-MCF51MM module is used stand-alone,
USB port (J17) is both the power source and the debugger
interface. When the TWR-MCF51MM module is assembled as a
Tower System, the USB port (J17) is only a OSBDM.
LEDs 1 to 4 correspond to silk-screened labels D9 to D12 on
the TWR-MCF51MM module.
