95 IDX addressing mode is also 100%, coded and simulated. creep 5580d 04h /t6507lp/
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 5581d 00h /t6507lp/
93 Opcode for BNE was wrong. creep 5581d 02h /t6507lp/
92 Absolute indexed mode working properly. All cases were simulated. creep 5581d 06h /t6507lp/
91 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page IS crossed is coded and simulated. creep 5581d 07h /t6507lp/
90 CMP, CPX and CPY affect carry flag (in this case it indicates a borrow) but they don't affect overflow. gabrieloshiro 5581d 07h /t6507lp/
89 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page is NOT crossed is coded and simulated. creep 5581d 07h /t6507lp/
88 Absolute indexed mode, READ TYPE instruction when page IS crossed is coded and simulated. creep 5581d 08h /t6507lp/
87 Absolute indexed mode, READ TYPE instruction when no page is crossed is coded and simulated. creep 5581d 23h /t6507lp/
86 Zero page indexed mode is working fine. creep 5582d 03h /t6507lp/
85 alu_x and alu_y variables created. gabrieloshiro 5582d 07h /t6507lp/
84 X and Y register are passed from ALU to FSM. gabrieloshiro 5582d 07h /t6507lp/
83 Completed HAL checking. All the relevant warnings and errors were removed. creep 5582d 08h /t6507lp/
82 Did some checking with HAL and fixed 20+ warnings and errors. creep 5583d 00h /t6507lp/
81 Decimal mode (BCD) is working. gabrieloshiro 5583d 00h /t6507lp/
80 Grouping some instructions that have the same behavioral. gabrieloshiro 5583d 01h /t6507lp/
79 ALU testbench added. gabrieloshiro 5583d 02h /t6507lp/
78 ZPG coded and simulated. creep 5583d 02h /t6507lp/
77 ZPG coded. Simulation is halfway. creep 5583d 03h /t6507lp/
76 ABS write instructions were not simulated.
Also added some initial ZPG simulation.
