Setting the PC

The program counter is the part of the processor that contains the address of the current machine instruction. (Actually, it contains the address of the first of the four bytes that make up the current instruction.) In the register display (top window) you see that the PC starts out at zero. This must be changed to 0x00400000, the address of the first instruction. To do this, select (click on) Simulator; Set Value in the menu bar.

In the set value dialog, type PC in the top text box and 0x00400000 in the bottom text box. Click on OK and the PC (in the register display) should change.
