100 IDY WRITE TYPE instructions are coded and simulated. creep 5589d 12h /
99 Only Package.v should be used. creep 5589d 12h /
98 Updated status and some comments. creep 5589d 12h /
97 Removed obsolete TODO. creep 5589d 12h /
96 IDY READ TYPE instructions are coded and simulated.
IDY WRITE TYPE instructions are coded but still requires simulation.		 creep 5592d 04h /
95 IDX addressing mode is also 100%, coded and simulated. creep 5592d 08h /
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 5593d 04h /
93 Opcode for BNE was wrong. creep 5593d 06h /
92 Absolute indexed mode working properly. All cases were simulated. creep 5593d 10h /
91 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page IS crossed is coded and simulated. creep 5593d 11h /
90 CMP, CPX and CPY affect carry flag (in this case it indicates a borrow) but they don't affect overflow. gabrieloshiro 5593d 11h /
89 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page is NOT crossed is coded and simulated. creep 5593d 11h /
88 Absolute indexed mode, READ TYPE instruction when page IS crossed is coded and simulated. creep 5593d 12h /
87 Absolute indexed mode, READ TYPE instruction when no page is crossed is coded and simulated. creep 5594d 03h /
86 Zero page indexed mode is working fine. creep 5594d 07h /
85 alu_x and alu_y variables created. gabrieloshiro 5594d 11h /
84 X and Y register are passed from ALU to FSM. gabrieloshiro 5594d 12h /
83 Completed HAL checking. All the relevant warnings and errors were removed. creep 5594d 12h /
82 Did some checking with HAL and fixed 20+ warnings and errors. creep 5595d 04h /
81 Decimal mode (BCD) is working. gabrieloshiro 5595d 04h /
