94 Relative addressing mode is almost 100% functional.
It just needs another test to check if the adrres_plus_index logic is not recalculating the pc in two consecutive cycles.
creep 5605d 02h /t6507lp/trunk/
93 Opcode for BNE was wrong. creep 5605d 04h /t6507lp/trunk/
92 Absolute indexed mode working properly. All cases were simulated. creep 5605d 09h /t6507lp/trunk/
91 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page IS crossed is coded and simulated. creep 5605d 09h /t6507lp/trunk/
90 CMP, CPX and CPY affect carry flag (in this case it indicates a borrow) but they don't affect overflow. gabrieloshiro 5605d 09h /t6507lp/trunk/
89 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page is NOT crossed is coded and simulated. creep 5605d 10h /t6507lp/trunk/
88 Absolute indexed mode, READ TYPE instruction when page IS crossed is coded and simulated. creep 5605d 10h /t6507lp/trunk/
87 Absolute indexed mode, READ TYPE instruction when no page is crossed is coded and simulated. creep 5606d 02h /t6507lp/trunk/
86 Zero page indexed mode is working fine. creep 5606d 05h /t6507lp/trunk/
85 alu_x and alu_y variables created. gabrieloshiro 5606d 10h /t6507lp/trunk/
84 X and Y register are passed from ALU to FSM. gabrieloshiro 5606d 10h /t6507lp/trunk/
83 Completed HAL checking. All the relevant warnings and errors were removed. creep 5606d 10h /t6507lp/trunk/
82 Did some checking with HAL and fixed 20+ warnings and errors. creep 5607d 02h /t6507lp/trunk/
81 Decimal mode (BCD) is working. gabrieloshiro 5607d 03h /t6507lp/trunk/
80 Grouping some instructions that have the same behavioral. gabrieloshiro 5607d 03h /t6507lp/trunk/
79 ALU testbench added. gabrieloshiro 5607d 04h /t6507lp/trunk/
78 ZPG coded and simulated. creep 5607d 04h /t6507lp/trunk/
77 ZPG coded. Simulation is halfway. creep 5607d 05h /t6507lp/trunk/
76 ABS write instructions were not simulated.
Also added some initial ZPG simulation.
creep 5607d 05h /t6507lp/trunk/
75 First working version! gabrieloshiro 5607d 05h /t6507lp/trunk/
