Description Bitwise XOR of
src
string and
dest

dest
string. If three
operands are specified, then logical XOR
src
string and
src1
string, store result
in
dest
string.

Example 4.14.86.1 XORS A0, A0~, *R2
XOR data memory string beginning at address in R2 to accumulator string A0~, put result in
accumulator string A0.
Example 4.14.86.2 XORS A3~, A3, *R1++R5
XOR data memory string beginning at address in R1 to accumulator string A3, put result in accumulator
string A3~. Add value in R5 to the value in R1 and store result in R1.
Example 4.14.86.3 XORS A1~, A1, 0x100 * 2
XOR program memory string beginning at word address 0x0100 to accumulator string A1, put result
in accumulator string A1~.
Example 4.14.86.4 XORS A2, A2~, A2
XOR accumulator string A2 with accumulator string A2~ string, put result in accumulator string A2.
