#Branch #Unconditional #PIC #microcontroller #BRAinstruction #SHORTbranches. This video explains the concept of unconditional branch instruction in PIC microcontrollers. Branch instructions are those instructions which are used to disturb the normal flow of program which is sequential means instructions are executed one after another. There are two types of unconditional instructions in pic microcontroller. one is short branches and other is long branch. In this lecture, only short branches are covered. BRA instruction is an important short branch instructions used in PIC Microcontroller. It is an unconditional branch which jumps whenever BRA instruction is encountered with in the code. BRA instruction is used with Label which can be any alpha numberical word except the already used keywords for instruction. BRA instruction jump to the label defined with in the code itself. It can Jump upward in the code means you can go to the previous instructions. BRA instructions can also be used to jump downward in the code that means Program counter will switch to instruction written afterwards. In this tutorial we are using BRA instruction to jump backward so it will repeat the previous instruction. it will produce the looping effect which is an important technique of Programming language.
