(Mini-)ALU [TOC]
==========

The following circuit demonstrates how the register file can be used together
with the adder and the status flag module for a simple ALU
(Arithmetical-Logical-Unit):

Tasks
=====

- Create this circuit in CircuitVerse.
- Familiarize yourself with how the circuit works. Try performing the following
  operations:

   - Write the bit pattern `1111` into register `%0`. The status flags should
     not be modified.
   - Write the bit pattern `0001` into register `%1`. The status flags should
     not be modified.
   - Add the contents of registers `%0` and `%1`, simultaneously updating the
     status flags.
   - Subtract the content of register `%1` from `%0`, simultaneously updating
     the status flags.
