CHAPTER 6 DETAILED RULES FOR EXECUTION INSTRUCTIONS

6.13 BNZ (Branch relative if Z = 0)/BNE (Branch if Not Equal)

Execute the next instruction if the Z-flag is 1 and the branch if it is 0. Branch address corresponds to the value of addition between the PC value (word value) of the next instruction and the value with rel code-extended (word value).

■BNZ (Branch relative if Z = 0)/BNE (Branch if Not Equal)

Operation

(Z) = 1: (PC) ← (PC) + 2 (Word addition)

(Z) = 0: (PC) ← (PC) + 2 + rel (Word addition)
