Either pair of registers <1> specifies the address
where the target array of data starts in the 64-Kbyte
area from F0000H to FFFFFH.
“byte” <2> specifies an offset within the array to
the target location in memory.

“word” <1> specifies the address where the target
array of word-sized data starts in the 64-Kbyte area
from F0000H to FFFFFH.
Either register <2> specifies an offset within the
array to the target location in memory.
