A
6502 opcode that performs a bitwise
exclusive OR. Pronounced like
Eeyore.
- Function: A ^ M => A
- Updates flags: S . . . . . Z .
- Opcode numbers:
(d,x) $41
dp $45
imm $49
abs $4D
(d),y $51
d,x $55
a,y $59
a,x $5D
Because 6502 is one of the only architectures that uses EOR as the official spelling, many assemblers support the synonym XOR.
