Lecture 4: The AVR's Status Register (SREG)

This video in the series created by Teaching Assistant Ph.D. student specifically for CEEN-1060 (Microcontroller Applications), shows these students about the AVR's status register (SREG).  It gives a brief description of each of the flags in SREG, and some of the associated instructions to manipulate them in some cases.  A very simple arithmetic example is performed by hand to explain how flags may get set.  The concept of carry and overflow are also discussed.

While the video might be useful in some respects to the general public, please note the video provides informati on that is specific to this course.
