Function
(1) Transfers in batch 16-bit data of n points from the device designated by
points from the device designated by
(2) Transfers can be accomplished even in cases where there is an overlap between the source
and destination device.
In the case of transmission to the smaller device number, transmission is from
transmission to the larger device number, transmission is from
However, as shown in the example below, when transferring data from R to ZR, or from ZR
to R, the range to be transferred (source) and the range of destination must not overlap.
Transfer from R to R, or from ZR to ZR can be performed without any problem.
• ZR transfer range ((specified head No. of ZR) to (specified head No. of ZR + the number
of transfers -1))
• R transfer range ((specified head No. of R + file register block No.
