2.3.11 Programming with PSDpro
Connect the PSDpro device programmer to your PC parallel port per the installation instructions.
Click on the ‘Device Programmer’ box in the design flow window. You will see this:
If this is the first use of the PSDpro, click on the ‘Htest’ icon to perform a test of the PSDpro and
the PC port. After testing, place a PSD813F into the socket of the PSDpro and click on the
‘Program’ icon (the *.obj file is automatically loaded when this process is invoked). The
messaging of PSDsoft will inform you when programming is complete. See Application Note 57
for details on all the features of this ‘Parallel Programming’ window.
This window is also helpful even if you do not have a PSDpro programmer. You can use this
window to see where the Address Translate utility of PSDsoft has placed the 68HC11 firmware
within physical memory of the PSD. For this design example, you can click on the EEPROM
icon in the tool bar, then scroll to the end segment EES1 to see the 68HC11 reset vector at
absolute MCU addresses FFFEh and FFFFh, which translates to PSD EEPROM physical
addresses 23FFEh and 23FFFh respectively. To see how all of your 68HC11 absolute addresses
translated into physical PSD memory addresses, see the report that PSDsoft generates under
‘View’ from the main toolbar, then select ‘Address Translation Report’. The ‘start’ and ‘stop’
addresses in the report are the absolute MCU system addresses that you have specified. The
addresses shown in square brackets are the direct physical addresses used by a device
programmer to access the memory elements of the PSD in a linear fashion (a special device
programming mode that the MCU cannot access).
3 Enhanced Design Example
This second design example builds upon the first to add enhanced features to this ISP capable
68HC11 system. The physical connections between the 68HC11 and PSD813F1 do not change,
but the memory map and PSDabel equations do. The focus of this enhanced design is to get the
