Recover Microcontroller ATmega644P Flash memory content is a process to extract ATmega644p MCU memory heximal by crack processor’s fuse bit;

To further ensure program security, alterations to the Watchdog set-up must follow timed sequences. The sequence for clearing WDE and changing time-out configuration is as follows:

(WDCE) and WDE. A logic one must be written to WDE regardless of the previous value of the WDE bit. (WDP) as desired, but with the WDCE bit cleared. This must be done in one operation.

The following code example shows one assembly and one C function for turning off the Watchdog Timer. The example assumes that interrupts are controlled (e.g. by disabling interrupts globally) so that no interrupts will occur during the execution of these functions if break Microcontroller pic16f628a content.

Note: If the Watchdog is accidentally enabled, for example by a runaway pointer or brown-out condition, the device will be reset and the Watchdog Timer will stay enabled. If the code is not set up to handle the Watchdog, this might lead to an eternal loop of time-out resets.

To avoid this situation, the application software should always clear the Watchdog System Reset Flag (WDRF) and the WDE control bit in the initialisation routine, even if the Watchdog is not in use. In the same operation, write a logic one to the Watchdog change enable bit to attack pic12f510 program.
