Description
XOR will perform a bit wise "xor" of the current ACC and the 24bit MASK specified within the instruction word. The instruction will invert ACC provided MASK equals $FFFFFF. (see also the pseudo opcode section)

Coding Example
XMASK EQU $AAAAAA ;
;
;-------------------------------------------
sof 0,0 ; Clear all bits within ACC
xor $0 ; Set all ACC bits
xor %01010101_01010101_01010101 ; Invert all even numbered bits
xor XMASK ; Invert all odd numbered bits
