Clone ATMEL ATMEGA1280V Microcontroller Flash Binary from its flash memory after break off atmega1280v mcu fuse bit and readout atmega1280v mcu firmware program from flash memory;
Port G is a 6-bit I/O port with internal pull-up resistors (selected for each bit). The Port G output buffers have sym- metrical drive characteristics with both high sink and source capability. As inputs, Port G pins that are externally pulled low will source current if the pull-up resistors are activated by cracking mcu atmega1280v flash memory. The Port G pins are tri-stated when a reset con- dition becomes active, even if the clock is not running.
Port H is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port H output buf- fers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port H pins that are externally pulled low will source current if the pull-up resistors are activated. The Port H pins are tri-stated when a reset condition becomes active, even if the clock is not running.
Port J is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port J output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port J pins that are externally pulled low will source current if the pull-up resistors are activated in case the chip atmega1280v flash memory content can be unlocked. The Port J pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port J also serves the functions of various special features of the ATmega1280v as listed.
