9.4.2 Computed GOTO
A computed GOTO is accomplished by adding an offset to the Program Counter
                (ADDWF PCL). When performing a table read using a computed
                GOTO method, care has to be exercised if the table location crosses
            a PCL memory boundary (each 256-byte block). Refer to application note AN556,
                “Implementing a Table Read”
            (DS00556).
