
The instruction is used to transfer the values in registers to new
registers. The values in the n registers starting from S are transferred to
the n registers starting from D . If n is not in the range available, only the
values in registers available will be transferred.

S : Source; D : Destination; n : Length

n is in the range of 1 to 512.


In order to prevent the error which results from the overlap between
source devices and destination devices, the values in the source
devices are transferred in the following way.
1. The device number of
S is greater than the device number of D . The
values in D20~D22 are transferred in the order
