XOR

Mnemonic Operation Instruction coding
XOR ACC ^ MASK MMMMMMMMMMMMMMMMMMMMMMMM000010000
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)

Parameters
Name Width Entry formats, range
M 24 Bit Binary

Hex ($000000 - $FFFFFF) Symbolic

Syntax

XOR M

Coding Example

<syntaxhighlight line="1"> 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 </syntaxhighlight>
