DESCRIPTION
bits, and stores the result in rdest. The value of rsrc2 determines which byte is selected, with rsrc2=0 selecting the
LSB of rsrc1 and rsrc2=3 selecting the MSB of rsrc1. If rsrc2 is not between 0 and 3 inclusive, the result of

modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 0x44332211, r40 = 1
r10 = 0, r60 = 0xddccbbaa, r70 = 2
r20 = 1, r60 = 0xddccbbaa, r70 = 2
r100 = 0xffffff7f, r110 = 0
