High-speed block transfer of file register
RBMOV(P)
Processing details
• Transfers in batch 16-bit data of n points from the device designated by (S) to location n points from the device designated
by (D).
• The transfer is available even if there is an overlap between the source and destination devices. For the transmission to the
smaller number of device, the data is transferred from (S). For the transmission to the larger number of device, the data is
transferred from (S)+(n-1). 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. (QnUDVCPU is excluded.)
• Universal model QCPU: Models other than Q00UJCPU
(S): Head number of the devices where the data to be transferred is stored (BIN 16 bits)
(D): Head number of the devices of transfer destination (BIN 16 bits)
n: Number of data to be transferred (BIN 16 bits)

• 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))
