Data Movement Instructions Section 5-17
5-17-10TRANSFER BITS – XFRB(––)
Limitations This instruction is available in the CQM1-CPU4@-E/-EV1 only.
The specified source bits must be in the same data area.
The specified destination bits must be in the same data area.
DM 6144 to DM 6655 cannot be used for D.
Description When the execution condition is OFF, XFRB(––) is not executed. When the
execution condition is ON, XFRB(––) copies the specified source bits to the
specified 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.
Note Up to 255 (FF) bits can be copied at one time.
Example In the following example, XFRB(––) is used to transfer 5 bits from IR 020 and
IR 021 to LR 00 and LR 01. The starting bit in IR 020 is D (13), and the start-
ing bit in LR 00 is E (14), so IR 02013 to IR 02101 are copied to LR 0014 to
LR 0102.
Flags ER: The specified source bits are not all in the same data area.
The specified destination bits are not all in the same data area.
