<p>A microcontroller performs a jump double register indirect instruction by determining the address of a procedure to execute using the contents of a designated pointer register as an index into a procedure address table located anywhere in the address space where each entry is an address of an entry point for the particular procedure to be executed. The address is retrieved and loaded into the microcontroller program counter resulting in a jump to the entry point of the procedure. The contents of the pointer register is post incremented to point at the next entry of the table and, as a result, the next procedure. The next execution of the instruction will cause a jump to the next procedure.</p> |
