===Kernel-Defined Traps=== |

Depending on the hardware, certain traps are built-in to perform certain tasks, such as reading a keyboard or mouse, or are user-defined. To create your own trap routine, you'll need to first write the routine, then store its address in the corresponding trap number. Trap 0 is stored at $000080, Trap 1 at $000084, and so on. The overflow trap is stored at address $00001C. |
