This is episode 2 of the bare metal programming series! In this video, we're taking a deep dive into the memory-mapped I/O mechanism that underpins the CPUs communication with the peripherals on the chip. We also discuss and explore interrupts and the interrupt vector table, as well where to find the fundamental information related to your chip: datasheets and reference manuals.

![Unsigned Numbers! [The Bits And Bytes Of Binary ep. 3]](https://i.ytimg.com/vi/TdPQ-1TEiNI/mqdefault.jpg "Unsigned Numbers! [The Bits And Bytes Of Binary ep. 3]
This mini series is all about binary. Over the course of the series, well be building a library that gives us precise control of every bit and operation.
Youll learn how the logical and arithmetic operations work, how different kinds of numbers are encoded, how to set, clear and toggle bits, and how we can create representations of structured binary data.
1. Bits
2. Operations
3. Unsigned Numbers
4. Addition
5. Zero Extension
6. Twos complement
7. Overflow Addition and Sign Extension
8. Shifting
9. Setting, Clearing, and Toggling Bits
10. Endianness
11. Structures
