Does anyone knows if I can work with a lookup table in the second half of a page??
I cann't understand why if I inc PC in that zone, let's say in address #10E, it jumps "nowhere land". 

 

For example, can I make this work? 

 

                      ;**** Page_0_Jmp_Table *****
                       ;
                        ISR_Origin  = $0                 ;
                        Page_0_Jmp_Table = $0F5   ;
                        Page_0   = $0a0                ;
                        Page_1   = $104                ;
                       ;=====================;
                       ;                                      ;

                       org Page_0_Jmp_Table         ; Address ($0F5)

                       ;                                      ;

                       ab_         jmp          ab       ;

                       ;=====================;
                       ;                                      ;
                       org Page_0                        ; Address ($0a0)

                       ;                                      ;

                       Main1       clr          w         ; Start
                                     call         ab_       ;
                                     jmp         $          ; End
                       ;---------------------------;
                        org Page_1                       ; Address ($100) Same page but second half.

                        ;                                     ;

                        ab           jmp        pc+w    ;
                                     retw        $40      ;
