5 Input/Output Connectors and Pin Usage Table
The following tables provide details on which MCF51MM256 pins are communicating with the TWR-
MCF51MM sensors, LEDs, switches and other I/O interfaces.
6 OSBDM
An on-board, MC9S08JM60 based OSBDM circuit provides a debug interface to the MCF51MM256.
The MC9S08JM60 is a USB-enabled microcontroller with an 8-bit HC9S08 core. The OSBDM circuit
provides a USB-to-debug interface that allows run-control and debugging of the MCF51MM256 target
device. The USB drivers required to communicate with the OSBDM are provided in development tools
such as Freescale CodeWarrior. When TWR-MCF51MM is used stand-alone, this single USB connection
can also be used for power.
6.1
The MC9S08JM60 device used in the OSBDM circuit is preprogrammed with OSBDM debugger
firmware and a USB Bootloader. The bootloader mode can be used to update the OSBDM debugger
firmware if an update becomes available. Jumper J12 determines which application will run following a
power-on reset. If the Bootloader Mode is chosen (jumper shunt on J12), the bootloader will be
