Execution [premodify AP if mod specified]
dest ⇐ dest XOR src (for two operands)
dest ⇐ src1 XOR src (for three operands)
PC ⇐ PC + w
Flags Affected dest is An: OF, SF, ZF, CF are set accordingly
dest is TFn: TFn bits in STAT register are set accordingly
src is {adrs}: TAG bit is set accordingly
src is {flagadrs}: TAG bit is set accordingly

Description Bitwise logical XOR of src and dest. Result is stored in dest. If three operands
are specified, then logical XOR src and src1, store the result in dest. Pre-
modification of accumulator pointers is allowed with some operand types.
Syntax Description
XOR An, {adrs} XOR RAM word to An
XOR An[~], An[~], imm16 [, next A] XOR immediate word to An[~], store result in An[~]
XOR An[~], An~, An [, next A] XOR An word to An~ word, store result in An[~]
XOR TFn, {flagadrs} XOR TFn (either TF1 or TF2) with memory tag, store result in TFn bit in
STAT
XOR TFn, {cc} [, Rx] XOR test condition with TFn (either TF1 or TF2) bit in STAT register. Rx
must be provided if cc is one of {RZP, RNZP, RLZP, RNLZP} to check if
the selected Rx is zero or negative. Rx should not be provided for other
conditionals.
