Function
if R4L ≠ 0 then
repeat @R5+ → @R6+
R4L – 1 → R4L
until
R4L = 0
else next;
Moves a data block according to parameters set in general registers
R4L, R5, and R6.
R4L: size of block (bytes)
R5: starting source address
R6: starting destination address
Execution of the next instruction starts as soon as the block transfer
is completed.
