The higher hexadecimal digit
(bit position 12 to 15) becomes 0.
Starting area D1 and ending area D2 should be:
− The same type of operand.
− D1
D2.
When the hexadecimal digit (4 bits) is shifted to the right,
− The data at the lower hexadecimal digit (bit positions 0 to 3) of the 16-bit data specified by D1 is
shifted out.
− The data at the higher hexadecimal digit (bit positions 12 to 15) in the 16-bit data specified by D2
becomes 0.
