Crack MCU ATMEGA2561 Flash Memory Protection and decrypt embedded dump file from microprocessor atmega2561, copy microcontroller atmega2561 program to new flash memory;
RESET, Reset pin: When the RSTDISBL Fuse is programmed, this pin functions as a normal I/O pin, and the part will have to rely on Power-on Reset and Brown-out Reset as its reset sources.
When the RSTDISBL Fuse is unpro- grammed, the reset circuitry is connected to the pin, and the pin can not be used as an I/O pin when crack atmega32 microcontroller flash memory. If PC6 is used as a reset pin, DDC6, PORTC6 and PINC6 will all read 0.
SCL, Two-wire Serial Interface Clock: When the TWEN bit in TWCR is set (one) to enable the Two-wire Serial Interface, pin PC5 is disconnected from the port and becomes the Serial Clock I/O pin for the Two-wire Serial Interface.
In this mode, there is a spike filter on the pin to suppress spikes shorter than 50 ns on the input signal, and the pin is driven by an open drain driver with slew-rate limitation by cloning atmega32l microprocessor memory data. PC5 can also be used as ADC input Channel 5. Note that ADC input channel 5 uses digital power
