Program Flow Instructions

This chapter introduces the MSP430 program flow instructions [1]. Program flow instructions alter the location of the program counter to enable looping or conditional execution of code. Program flow instructions are what gives a computer program the ability to make decisions about what to do next (i.e., what code to execute) based on input conditions or the results of certain operations. Examples of program flow instructions are provided to help in understanding how they impact the program counter. Examples are also given on how to implement common programming constructs such as loops and decision statements. It is intended that the reader is coding the examples using the MSP430FR2355 LaunchPad™ board as they go through this chapter.
