XFRB(062) transfers up to 255 consecutive

bits from the source words (beginning with bit

l of S) to the destination words (beginning with

bit m of D).

The beginning bits and number of bits are

specified in C, as shown in the following

• Up to 255 bits of data can be transferred per execution of XFRB(062).

• It is possible for the source words and destination words to overlap. By transferring data overlapping

several words, the data can be packed more efficiently in the data area. (This is particularly useful

when handling position data for position control.)

• Since the source words and destination words can overlap, XFRB(062) can be combined with

ANDW(034) to shift m bits by n spaces.

• Be sure that the source words and destination words do not exceed the end of the data area.

• When the number of transfer bits (n of C) is 0, transfer does not take place.

• Bits in the destination words that are not overwritten by the source bits are left unchanged.

Example Programming

When CIO 0.00 is ON in the following example, the 20 bits beginning with CIO 200.06 are copied to the

20 bits beginning with CIO 300.
