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 the mini-USB
port (J14) on the TWR-SER module.
The S08MM128 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-

S08MM128 is used for programming
and debugging the S08MM128 MCU.
The debugger interface is the Freescale

USB. The TWR-S08MM128 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-S08MM128 USB. Do not
NOTE: When the TWR-S08MM128 module is used stand-alone,
USB port (J17) is both the power source and the debugger
interface. When the TWR-S08MM128 module is assembled as
a Tower System, the USB port (J17) is only a OSBDM.
