102 Some early modifications to support the special stack instructions. creep 5624d 17h /
101 Absolute indirect addressing mode is coded and simulated. creep 5624d 20h /
100 IDY WRITE TYPE instructions are coded and simulated. creep 5624d 21h /
99 Only Package.v should be used. creep 5624d 22h /
98 Updated status and some comments. creep 5624d 22h /
97 Removed obsolete TODO. creep 5624d 22h /
96 IDY READ TYPE instructions are coded and simulated.
IDY WRITE TYPE instructions are coded but still requires simulation.		 creep 5627d 13h /
95 IDX addressing mode is also 100%, coded and simulated. creep 5627d 17h /
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 5628d 14h /
93 Opcode for BNE was wrong. creep 5628d 15h /
92 Absolute indexed mode working properly. All cases were simulated. creep 5628d 20h /
91 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page IS crossed is coded and simulated. creep 5628d 20h /
90 CMP, CPX and CPY affect carry flag (in this case it indicates a borrow) but they don't affect overflow. gabrieloshiro 5628d 21h /
89 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page is NOT crossed is coded and simulated. creep 5628d 21h /
88 Absolute indexed mode, READ TYPE instruction when page IS crossed is coded and simulated. creep 5628d 21h /
87 Absolute indexed mode, READ TYPE instruction when no page is crossed is coded and simulated. creep 5629d 13h /
86 Zero page indexed mode is working fine. creep 5629d 16h /
85 alu_x and alu_y variables created. gabrieloshiro 5629d 21h /
84 X and Y register are passed from ALU to FSM. gabrieloshiro 5629d 21h /
83 Completed HAL checking. All the relevant warnings and errors were removed. creep 5629d 22h /
