 Define what you mean by 7h?

 A jump table in a 16C84/ 16F84 may be any length up to the whole of
memory.  The technique involves a 16-bit add of the jump address to the
base address (constant) of the table, with the most significant byte
stored in PCLATH, and the least significant put in W then execution of
 MOVWF PCL.
