The chip chosen by the customer is MC56F82723. Is there any method to read the program of the chip through JTAG?
Yes, you can download the Flash programming tools from the link:
PROGDSC | Flash/EEPROM Programmer Software for DSC devices | PEmicro
With the tools and MultiLink Universal device, you can read code or data and program the on-chip flash of MC56F82xxx.
The MC56F82xxx supports the flash security function, when you write a specific byte to a specific address of flash, the JTAG is blocked to protect cusomer IP.
Hope it can help you
