113 Timescale was unified. gabrieloshiro 5587d 06h /t6507lp/
112 Created a global timescale file for the project. creep 5587d 06h /t6507lp/
111 Performed some linting after coding was finished. creep 5587d 22h /t6507lp/
110 All addressing modes and special instructions have been coded and simulated. The file still requires coments, linting and some coverage. creep 5587d 23h /t6507lp/
109 PLA and PLP are coded and simulated. creep 5588d 02h /t6507lp/
108 PHA and PHP are coded and simulated. creep 5588d 02h /t6507lp/
107 The RTS instruction is working fine. Coded and simulated. creep 5588d 03h /t6507lp/
106 First stable version. Things seems to be working. Simulation is currently at 20%. gabrieloshiro 5588d 04h /t6507lp/
105 The RTI instruction is working fine. Coded and simulated. creep 5588d 04h /t6507lp/
104 The BRK instruction is working. The reset vector was tested also. creep 5588d 06h /t6507lp/
103 Some early modifications to support the special stack instructions. creep 5588d 23h /t6507lp/
102 Some early modifications to support the special stack instructions. creep 5589d 02h /t6507lp/
101 Absolute indirect addressing mode is coded and simulated. creep 5589d 05h /t6507lp/
100 IDY WRITE TYPE instructions are coded and simulated. creep 5589d 06h /t6507lp/
99 Only Package.v should be used. creep 5589d 07h /t6507lp/
98 Updated status and some comments. creep 5589d 07h /t6507lp/
97 Removed obsolete TODO. creep 5589d 07h /t6507lp/
96 IDY READ TYPE instructions are coded and simulated.
IDY WRITE TYPE instructions are coded but still requires simulation.		 creep 5591d 23h /t6507lp/
95 IDX addressing mode is also 100%, coded and simulated. creep 5592d 02h /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 5592d 23h /t6507lp/
93 Opcode for BNE was wrong. creep 5593d 00h /t6507lp/
92 Absolute indexed mode working properly. All cases were simulated. creep 5593d 05h /t6507lp/
91 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page IS crossed is coded and simulated. creep 5593d 05h /t6507lp/
90 CMP, CPX and CPY affect carry flag (in this case it indicates a borrow) but they don't affect overflow. gabrieloshiro 5593d 06h /t6507lp/
89 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page is NOT crossed is coded and simulated. creep 5593d 06h /t6507lp/
88 Absolute indexed mode, READ TYPE instruction when page IS crossed is coded and simulated. creep 5593d 07h /t6507lp/
87 Absolute indexed mode, READ TYPE instruction when no page is crossed is coded and simulated. creep 5593d 22h /t6507lp/
86 Zero page indexed mode is working fine. creep 5594d 01h /t6507lp/
85 alu_x and alu_y variables created. gabrieloshiro 5594d 06h /t6507lp/
84 X and Y register are passed from ALU to FSM. gabrieloshiro 5594d 06h /t6507lp/
