FUNCTION
DESCRIPTION
operands are considered signed integers.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 2, r20 = 1
r10 = 0, r60 = 0x100, r30 = 2
r20 = 1, r60 = 0x100, r40 = 0xffffff9c
r10 = 0, r40 = 0xffffff9c
r20 = 1, r60 = 0x100
r10 = 0, r70 = 0x456789

Initial Values
operation writes 0 into rdest if the value of rsrc1 is not zero; otherwise, rsrc2 is copied to rdest. The
operation optionally takes a guard, specified in rguard. If a guard is present, its LSB controls the
