Description
This instruction moves a block of data from the memory location specified in general register R5
to the memory location specified in general register R6. General register R4L gives the byte
length of the block.
Data are transferred a byte at a time. After each byte transfer, R5 and R6 are incremented and
R4L is decremented. When R4L reaches 0, the transfer ends and the next instruction is
executed. No interrupt requests are accepted during the data transfer.
At the end of this instruction, R4L contains H'00. R5 and R6 contain the last transfer address +1.
The memory locations specified by general registers R5 and R6 are read before the block
transfer is performed.
