Programming code with BDM

[lsi]

With P&E BDM, when we download software into flash memory (HCS12 or S08) is there a way to keep un-erase some specific flash pages?  In our design, these pages are used for calibration parameters and we dont want to enter them each time we upgrade the device software.

Thanks

On MCU's with more than one flash array or flash+EEPROM you can make debugger not erasing specific flash arrays or EEPROM. On others and in case you need to protect just one sector of flash use save-restore method using debugger *.cmd files:
