Break ATMEGA64L Secured Microcontroller Flash Memory and clone the avr mcu atmega64l heximal content to new MCU, read the firmware program out from atmega64l microprocessor flash and eeprom memory;

Each port pin consists of 3 Register bits: DDxn, PORTxn, and PINxn. As shown in “Register Description” on page 69, the DDxn bits are accessed at the DDRx I/O address, the PORTxn bits at the PORTx I/O address, and the PINxn bits at the PINx I/O address.

The DDxn bit in the DDRx Register selects the direction of this pin. If DDxn is written logic one, Pxn is configured as an output pin when recover protective microprocessor atmega16 firmware. If DDxn is written logic zero, Pxn is configured as an input pin.

If PORTxn is written logic one when the pin is configured as an input pin, the pull-up resistor is activated. To switch the pull-up resistor off, PORTxn has to be written logic zero or the pin has to be configured as an output pin.

The port pins are tri-stated when a reset condition becomes active, even if no clocks are running. If PORTxn is written logic one when the pin is configured as an output pin to break atmega16l locked mcu flash memory, the port pin is driven high (one). If PORTxn is written logic zero when the pin is configured as an output pin, the port pin is driven low (zero).
