z When operation control "EN" = 1 or "EN↑" ( P instruction) has a
transition from 0 to 1, this instruction will performs a logic XOR (if
the 2 bits are different, then the result will be 1, otherwise it will be
0)between 2 source matrixes with a length of L, Ma and Mb. The
result will then be stored back into the destination matrix Md, which
also has a length of L. For example the XOR operation is done by
bits with the same bit numbers - for example, if Ma
0
= 0, Mb
0
= 1,
then Md
0
= 1; if Ma
1
= 1, Mb
1
= 1, then Md
1
= 0; etc, right up until
XOR reaches Ma
16L-1
and Mb
16L-1
.

z In the program at left, when X0 goes from 0→1, will
perform a XOR operation between matrix Ma, comprised
by R0 to R4, and matrix Mb, comprised by R10 to R14.
The results will then be stored in destination matrix Md,
comprised by R20 to R24. The results are shown at right
in the diagram below.
