its a treadmill motorcontroller ,i'm not sure you have any idea how i can find out?
That is true since most of the companies that use firmware in a microcontroller have it read protected so you can't do what you are trying to do. If you can get the contents of the Program memory that may only be part of the task since there is also the non-volatile EEPROM and configuration registers to deal with. Trying to clone them for whatever purposes may in fact be illegal and subject you to civil and criminal penalties. I certainly would not be asking for help on a public forum since the operators will more than likely comply with a subpoena for your information.
