DESCRIPTION
range [2
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 = 0x10, r40 = 0x20
r10 = 0, r30 = 0x10, r40 = 0x20
r20 = 1, r30 = 0x10, r40 = 0x20
r50 = 0x40000000, r90 = 2
r80 = 0xffffffff
r70 = 0x80000000, r90 = 2
