 This project is an AVR emulator written in Haskell, utilizing CABAL for building and managing dependencies. The emulator simulates a basic AVR microcontroller environment with a 2KB memory space starting from address `0x0000`. The emulator currently supports a subset of AVR instructions, and you can load and execute assembly programs to test its functionality.
