Copy Locked Microcontroller PIC12F617 Flash Program
Copy Locked Microcontroller PIC12F617 Flash Program needs to break down the protection over secured MCU PIC12F617 flash memory and then extract embedded heximal file from PIC12F617 processor;
The Timer1 oscillator shares the T1OSI and T1OSO pins with the PGD and PGC pins used for programming and debugging.
When using the Timer1 oscillator, In-Circuit Serial Programming (ICSP) may not function correctly (high voltage or low voltage), or the In-Circuit Debugger (ICD) may not communicate with the controller to copy pic12f519 mcu flash memory firmware. As a result of using either ICSP or ICD, the Timer1 crystal may be damaged.
If ICSP or ICD operations are required, the crystal should be disconnected from the circuit (disconnect either lead) or installed after programming by replicating microchip pic12f509 flash firmware. The oscillator loading capacitors may remain in-circuit during ICSP or ICD operation.
