112 Created a global timescale file for the project. creep 5575d 08h /
111 Performed some linting after coding was finished. creep 5575d 23h /
110 All addressing modes and special instructions have been coded and simulated. The file still requires coments, linting and some coverage. creep 5576d 01h /
109 PLA and PLP are coded and simulated. creep 5576d 03h /
108 PHA and PHP are coded and simulated. creep 5576d 04h /
107 The RTS instruction is working fine. Coded and simulated. creep 5576d 05h /
106 First stable version. Things seems to be working. Simulation is currently at 20%. gabrieloshiro 5576d 05h /
105 The RTI instruction is working fine. Coded and simulated. creep 5576d 05h /
104 The BRK instruction is working. The reset vector was tested also. creep 5576d 07h /
103 Some early modifications to support the special stack instructions. creep 5577d 01h /
102 Some early modifications to support the special stack instructions. creep 5577d 04h /
101 Absolute indirect addressing mode is coded and simulated. creep 5577d 07h /
100 IDY WRITE TYPE instructions are coded and simulated. creep 5577d 08h /
99 Only Package.v should be used. creep 5577d 09h /
98 Updated status and some comments. creep 5577d 09h /
97 Removed obsolete TODO. creep 5577d 09h /
96 IDY READ TYPE instructions are coded and simulated.
IDY WRITE TYPE instructions are coded but still requires simulation.
creep 5580d 00h /
95 IDX addressing mode is also 100%, coded and simulated. creep 5580d 04h /
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 /
93 Opcode for BNE was wrong. creep 5581d 02h /
