DESCRIPTION
arguments r src1 and r src2 are considered unsigned integers.
modification of the destination register. If the LSB of r guard is 1, r dest is written; otherwise, r dest is not changed.
EXAMPLES
r30 = 0x80, r40 = 0x7f
r10 = 0, r60 = 0x12345678,
r70 = 0xabc
r20 = 1, r60 = 0x12345678,
r70 = 0xabc
