Interrupts

This chapter describes CPU interrupts, including reset and the nonmaskable interrupt (NMI). It details the related CPU control registers and their functions in controlling interrupts. It also describes interrupt processing, the method the CPU uses to detect automatically the presence of interrupts and divert program execution flow to your interrupt service code. Finally, the chapter describes the programming implications of interrupts.
