Decode Protected Microcontroller ATmega128 Flash Software after breaking atmel chip atmega128 mcu fuse bit and unlock atmega128 microprocessor flash memory data and eeprom memory program;
For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses should never be written.
I/O Registers within the address range 0x00 – 0x1F are directly bit-accessible using the SBI and CBI In these registers, the value of single bits can be checked by using the SBIS and SBIC instructions to readout ic chip atmega128 mcu flash firmware.
Some of the Status Flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI instructions will only operate on the specified bit, and can therefore be used on registers containing such Status The CBI and SBI instructions work with registers 0x00 to 0x1F only.
When using the I/O specific commands IN and OUT, the I/O addresses 0x00 – 0x3F must be used. When addressing I/O Registers as data space using LD and ST instructions, 0x20 must be added to these The ATmega165P is a com- plex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for the IN and OUT instructions when extracting microcontroller atmega128p flash binary. For the Extended I/O space from 0x60 – 0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used.
