We could continue this Stepping process and watch each register being

loaded, as the instructions are executed one-by-one, but for the purposes of

this tutorial we will leave the Stepping process and continue executing the

program without stepping.

12 In the tutorial.asm window, scroll down to the

jrs 0,drbcopy,lowbit

instruction and click it once - this highlights the instruction in blue. This

instruction is in the Timer Interrupt Service Routine and will not be reached until

the timer interrupts the program (which means that it counts down to zero).

13 Click the Break button - this causes the instruction to be displayed in bold (see

Figure 15

) which means a breakpoint has been set at this instruction.
