Function
(1) Transfers in batch 16-bit data of n points from the device designated by
designated by .
D
(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
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. 32768) to (specified head No. of R + file register
block No. 32768 + the number of transfers -1))
Example
Transfer ranges of ZR and R overlap when transferring 10000 blocks of data from ZR30000 (source) to R10 (block No.1
of the destination).
• ZR transfer range
• R transfer range
Therefore, the range 32778 to 39999 overlaps and the data is not correctly transferred.
