WebIf we set the PC to x3000 and hit "Next", we will execute the AND go to the JSR instruction. Hitting "Next" again will execute everything in the function call, but the simulator won't stop until we reach the NOT instruction, i.e. after the function has returned. Hitting "Next" again will follow the branch and take us to the START label. WebAn example of this would be a store instruction. You need one clock cycle to set MDR and another to set MAR. LD.CC. Any time you do an instruction that changes the value of a register in the register file, you need to set the condition codes because there is a possibility that we require the sign of that value to determine branching (BR) logic. celebrities with pillow face
