6.6 Data Transfer Instructions
Transferring n-bit data
BLKMOVB(P)
These instructions block transfer the bit data of (n) point(s) from the device specified by (s) to the bit data of (n) point(s) from
(d).
■Descriptions, ranges, and data types
■Applicable devices
*1 T, ST, C cannot be used.
• These instructions block transfer the bit data of (n) point(s) from the device specified by (s) to the bit data of (n) point(s)
from the device specified by (d).
• Data can be transferred even when the device range of the transfer-source device and transfer-destination device is
overlapping.
