Programming the MCU
To download the software into the microcontroller, use an USB/PARALLEL to JTAG converter. Before
downloading new software, stop the motor by the START/STOP switch and execute the Debug command
as shown in Figure 6-4.
Figure 6-4. Execute Debug Command
CAUTION
The JTAG connector does not provide galvanic isolation. The application
hardware set-up has to be disconnected from high-voltage if a JTAG
connection is required. To debug the application, or to download code to the
device flash memory using JTAG, use a low voltage +12V power supply
connected to the J12 connector on the MC56F8013/23 Controller Board!
Another option is to use a JTAG or USB optoisolator for downloading the
application code, or to use the FreeMASTER application.
