Appendix A: Other Data Representations

The content of this appendix is intended to expand on what was covered in Architecture of the Atmel ATmega 328 Microcontroller.

The text is supported by four short videos which present the material and cover additional information and methods about how data is represented on a microcontroller; these include, two’s complement, binary coded decimal, binary fractions and A.S.C.I.I.

You will find the videos on Canvas on page Two’s complement, BCD, Binary Fractions and A.S.C.I.I.
