We can reverse engineering ATMEL AVR Chip ATMEGA32A program file, please view the ATMEL AVR Chip ATMEGA32A features for your reference:
The 9th bit of the program counter will be forced to a ‘0’ by any instruction that writes to the PC except for GOTO. See Section 4.7 “Program Counter”. When an I/O register is modified as a function of itself (e.g. MOVF PORTB, 1), the value used will be that value present on the pins themselves. For example, if the data latch is ‘1’ for a pin configured as input and is driven low by an external device, the data will be written back with a ‘0’.
The instruction TRIS f, where f = 6, causes the contents of the W register to be written to the tri-state latches of PORTB. A ‘1’ forces the pin to a high-impedance state and disables the output buffers.
If this instruction is executed on the TMR0 register (and where applicable, d = 1), the prescaler will be cleared (if assigned to TMR0).

The MPLAB IDE software brings an ease of software development previously unseen in the 8/16-bit ATMEL AVR Chip market. The MPLAB IDE is a Windows® operating system-based application that contains:
· A single graphical interface to all debugging tools after Reverse Engineering ATMEL AVR Chip ATmega32A Program File
– Simulator
– Programmer (sold separately)
– Emulator (sold separately)
– In-Circuit Debugger (sold separately)
· A full-featured editor with color-coded context
· A multiple project manager
· Customizable data windows with direct edit of contents
· High-level source code debugging
· Visual device initializer for easy register initialization
· Mouse over variable inspection
· Drag and drop variables from source to watch windows
· Extensive on-line help
· Integration of select third party tools, such as
HI-TECH Software C Compilers and IAR C Compilers
The MPLAB IDE allows you to:
· Edit your source files (either assembly or C)
· One touch assemble (or compile) and download to PIC MCU emulator and simulator tools (automatically updates all project information)
· Debug using:
– Source files (assembly or C)
– Mixed assembly and C
– Machine code
MPLAB IDE supports multiple debugging tools in a single development paradigm, from the cost-effective simulators, through low-cost in-circuit debuggers, to full-featured emulators. This eliminates the learning curve when upgrading to tools with increased flexibility and power when Reverse Engineering Microcontroller.
