101 Absolute indirect addressing mode is coded and simulated. creep 5881d 20h /t6507lp/
100 IDY WRITE TYPE instructions are coded and simulated. creep 5881d 21h /t6507lp/
99 Only Package.v should be used. creep 5881d 21h /t6507lp/
98 Updated status and some comments. creep 5881d 21h /t6507lp/
97 Removed obsolete TODO. creep 5881d 21h /t6507lp/
96 IDY READ TYPE instructions are coded and simulated.
IDY WRITE TYPE instructions are coded but still requires simulation.		 creep 5884d 13h /t6507lp/
95 IDX addressing mode is also 100%, coded and simulated. creep 5884d 17h /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 5885d 13h /t6507lp/
93 Opcode for BNE was wrong. creep 5885d 15h /t6507lp/
92 Absolute indexed mode working properly. All cases were simulated. creep 5885d 19h /t6507lp/
91 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page IS crossed is coded and simulated. creep 5885d 20h /t6507lp/
90 CMP, CPX and CPY affect carry flag (in this case it indicates a borrow) but they don't affect overflow. gabrieloshiro 5885d 20h /t6507lp/
89 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page is NOT crossed is coded and simulated. creep 5885d 20h /t6507lp/
88 Absolute indexed mode, READ TYPE instruction when page IS crossed is coded and simulated. creep 5885d 21h /t6507lp/
87 Absolute indexed mode, READ TYPE instruction when no page is crossed is coded and simulated. creep 5886d 12h /t6507lp/
86 Zero page indexed mode is working fine. creep 5886d 16h /t6507lp/
85 alu_x and alu_y variables created. gabrieloshiro 5886d 20h /t6507lp/
84 X and Y register are passed from ALU to FSM. gabrieloshiro 5886d 21h /t6507lp/
83 Completed HAL checking. All the relevant warnings and errors were removed. creep 5886d 21h /t6507lp/
82 Did some checking with HAL and fixed 20+ warnings and errors. creep 5887d 13h /t6507lp/
