Description/function
The TWR-S08PT60 is a development tool for the MC9S08PT60 rugged 5V 8-bit MCUs and is designed to highlight the touch sensing and motor control capabilities of the MCU
For Use With
Freescale Tower System
6 OSBDM
An on‐board, MC9S08JM60‐based OSBDM circuit provides a debug interface to the MC9S08PT60. It
can also function as a virtual RS232 port as described in Section 3.4 RS232 Interface.
The MC9S08JM60 is a USB‐enabled microcontroller with an 8‐bit S08 core. The OSBDM circuit provides
a USB‐to‐debug interface that allows run‐control and debugging of the MC9S08PT60 devices on the
TWR‐S08PT60 Tower System module or on the user’s target boards. For more information on how to
configure jumpers for the OSBDM to support user’s target board, please consult Section 3.3 Debug
Interface.
The USB drivers required to communicate with the OSBDM are provided in development tools, such as
Freescale CodeWarrior software. www.freescale.com/codewarrior
When TWR‐S08PT60 is used stand‐alone, this single USB connection can also be used to power the
board.
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 J13 determines which application will run following a
power‐on reset. If the Bootloader Mode is chosen (jumper shunt on J13), the bootloader will be
executed, allowing in‐circuit reprogramming of the JM60 Flash memory via USB. Refer to Application
Note AN3561 on the Freescale website (http://www.freescale.com) for details on the USB Bootloader.
The USB Bootloader communicates with a GUI application running on a host PC. The GUI application
can be found on the Freescale website; search keyword “JM60 GUI.” Refer to section 2.5 and 3.3 of
AN3561 for details on installing and running the application.
7 BDM Interface (Optional)
Both MC9S08PT60 and MC9S08JM60 have an on‐chip background debug module. The user can choose
to bypass the USB OSBDM interface and use the BDM interface for debugging and programming the
corresponding chip instead. The BDM interface for MC9S08PT60 is at J23 header and MC9S08JM60 is
at J19 from the TWR‐S08PT60 module. The user needs a P&E USB BDM MULTILINK in order to use this
interface. This is a repeat function of the OSBDM and is not required.
6.1
The JM60 GUI Installer should run before connecting the OSBDM in Bootloader Mode
Bootloader Mode For MC9S08JM60
to a host USB port. Otherwise, the JM60 USB device will not be recognized and the
proper drivers will not be loaded.
