S : the head ID of source devices to be split
D : the head ID of storage devices for the split result
n : the number of bytes to be split
When X0 = “OFF” → “ON”, the instruction separates the contents of D10~D11 and D12's lower byte into 5 bytes
of data, then stores those bytes to 5 16-bit word components D20~D24. Since it is no data for all the upper bytes
of D20~D23, these bytes will be filled in 00H.
This instruction splits the consecutive byte devices which are started from the lower byte of , then store
the split result to the lower bytes of devices those are started from .
