GETTING STARTED
The M68EVB912C32 single board computer is a fully assembled, fully functional development
board for the Motorola MC9S12C32 microcontroller. Provided with wall plug power supply,
support disk, and serial cable. Support software for this development board is provided for
Windows 95/98/NT/2000/XP operating systems.
Development board users should also be familiar with the hardware and software operation of
the target HCS12 device, refer to the provided Motorola User Manual for the device and the
HCS12 Reference Manual for details. The EVB board purpose is to promote the features of
the 9S12C32 device or to assist the user in quickly developing an application with a known
working environment. Users should be familiar with memory mapping, memory types, and
embedded software design for the quickest successful application development.
Application development may be performed by applying the provided embedded serial
interface
Debug Monitor
, or by applying a compatible HCS12 BDM cable with supporting host
software. The debug monitor dedicates the SCI serial port as its connection to the host PC and
does not use the traditional background debug mode, thus eliminating the necessity for a
background debug mode cable.
The
Debug Monitor
in conjunction with a program running on a host personal computer (PC)
provides an effective and low cost debug method. Debug monitor operation enables a user to
erase device FLASH memory, program FLASH memory, load application programs, and
debug the application programs. Free host software is available for execution on a PC as an
interface to the monitor.
Debug monitor firmware is provided in the development board HC12 device internal flash
memory and applies some HC12 resources for operation. See the Monitor commands
application note from Motorola for details and the Debug Monitor chapter in this manual for
more information. User applications operated under monitor control may be configured for
dedicated operation by applying the User Reset Vector (0xF7FE/F) and programming the
application into the device flash. The monitor will remain in protected flash memory for future
use if needed.
M68EVB912C32 STARTUP
1) Apply power to the EVB board with the provided wall-plug power supply.
2) Install the provided serial cable between the EVB board COM1 port and an available COM
port on the host PC.
3) Install monitor hosting software on the host PC and launch.
4) Set the EVB board ON - OFF switch to the ON position and verify the POWER indicator is
ON. The EVB is ready to use.
5) Note that if the User Reset vector is programmed, the SW1_EN option jumper must be
installed and SW1 position 6 set to the ON position to enable the monitor.
