These things have changed from 6502 to 65C02:<BR>
|
|
<BR>
|
|
- new instructions.<BR>
|
|
- new adressing modes for a few instrucions.<BR>
|
|
- one adressing mode for fetch-modify-write instructions has been optimized, so it takes 1 less cycle in some cases.<BR>
|
|
- flags now work correctly in BCD mode (takes 1 additional cycle).<BR>
|
|
- absolute-indirect adressing mode now also works on a page boundary (also 1 additional cycle).<BR>
|
|
- BRK also affects the decimal flag now.<BR>
|
|
- illegal opcodes perform a NOP.<BR>

Another version of this processor, called 65SC02, doesn't have the single-bit instructions BBR/BBS/RMB/SMB.<BR>

INC and DEC now have implied adressing modes.<BR>

All major instructions (ORA, ADC, STA...) now also feature the indirect-zeropage adressing mode without index.<BR>

JMP features a new absolute-indirect-indexed adressing mode.<BR>
|
