One very obvious use case is synchronizing program flow with external (hardware) events. The main use case of the HALT instruction is thus "wait for an interrupt". WebThe processor copies the instruction data captured from the RAM. 2. Decode: Decoded captured data is transferred to the unit for execution. 3. Execute: Instruction is finally executed. The result is then registered in the processor or RAM (memory address).

It's rather boring; however, note the negative offset in the BRp LOOP instruction. That instruction is located at x300C which means the PC will be x300D when it is executed. The target, LOOP, is located at x3004, so the offset will be x3004-x300D, or -9.
