107 The RTS instruction is working fine. Coded and simulated. creep 5576d 04h /t6507lp/trunk/rtl/
106 First stable version. Things seems to be working. Simulation is currently at 20%. gabrieloshiro 5576d 05h /t6507lp/trunk/rtl/
105 The RTI instruction is working fine. Coded and simulated. creep 5576d 05h /t6507lp/trunk/rtl/
104 The BRK instruction is working. The reset vector was tested also. creep 5576d 07h /t6507lp/trunk/rtl/
103 Some early modifications to support the special stack instructions. creep 5577d 00h /t6507lp/trunk/rtl/
102 Some early modifications to support the special stack instructions. creep 5577d 03h /t6507lp/trunk/rtl/
101 Absolute indirect addressing mode is coded and simulated. creep 5577d 07h /t6507lp/trunk/rtl/
100 IDY WRITE TYPE instructions are coded and simulated. creep 5577d 08h /t6507lp/trunk/rtl/
99 Only Package.v should be used. creep 5577d 08h /t6507lp/trunk/rtl/
98 Updated status and some comments. creep 5577d 08h /t6507lp/trunk/rtl/
97 Removed obsolete TODO. creep 5577d 08h /t6507lp/trunk/rtl/
96 IDY READ TYPE instructions are coded and simulated.
IDY WRITE TYPE instructions are coded but still requires simulation.		 creep 5580d 00h /t6507lp/trunk/rtl/
95 IDX addressing mode is also 100%, coded and simulated. creep 5580d 03h /t6507lp/trunk/rtl/
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 /t6507lp/trunk/rtl/
93 Opcode for BNE was wrong. creep 5581d 01h /t6507lp/trunk/rtl/
92 Absolute indexed mode working properly. All cases were simulated. creep 5581d 06h /t6507lp/trunk/rtl/
91 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page IS crossed is coded and simulated. creep 5581d 06h /t6507lp/trunk/rtl/
90 CMP, CPX and CPY affect carry flag (in this case it indicates a borrow) but they don't affect overflow. gabrieloshiro 5581d 07h /t6507lp/trunk/rtl/
89 Absolute indexed mode, READ_MODIFY_WRITE TYPE instruction when page is NOT crossed is coded and simulated. creep 5581d 07h /t6507lp/trunk/rtl/
88 Absolute indexed mode, READ TYPE instruction when page IS crossed is coded and simulated. creep 5581d 08h /t6507lp/trunk/rtl/
