Limitations The specified source bits must be in the same data area.
The specified destination bits must be in the same data area.
Description When the execution condition is OFF, XFRB(62) is not executed. When the exe-
cution condition is ON, XFRB(62) copies the specified source bits to the speci-
fied destination bits. The two rightmost digits of C specify the starting bits in S
and D and the leftmost two digits indicate the number of bits that will be copied.
