Reverse ATMEGA64 Microcomputer Flash Memory
Reverse ATMEGA64 Microcomputer Flash Memory and recover atmega64 mcu flash embedded heximal out from its flash memory and eeprom memory, read data out from microcontroller atmega64 memory;
If Interrupt Vectors are placed in the Boot Loader section and Boot Lock bit BLB02 is programmed, interrupts are disabled while executing from the Application section by breaking atmega16l locked mcu flash memory. If Interrupt Vectors are placed in the Application section and Boot Lock bit BLB12 is programed, interrupts are disabled while executing from the Boot Loader section.
The IVCE bit must be written to logic one to enable change of the IVSEL bit. IVCE is cleared by hardware four cycles after it is written or when IVSEL is written. Setting the IVCE bit will disable interrupts, as explained in the IVSEL description above.
All AVR ports have true Read-Modify-Write functionality when used as general digital I/O ports. This means that the direction of one port pin can be changed without unintentionally changing the direction of any other pin with the SBI and CBI instructions in order to recover protective microprocessor atmega16 firmware. The same applies when changing drive value (if configured as output) or enabling/dis- abling of pull-up resistors (if configured as input).
