Function
SFTBR(P)
(1) This instruction shifts the n1 bits data in the devices starting from the device specified by
to the right by n2 bits.
n1=10, n2=4

(2) n1 and n2 are specified under the condition that n1 is larger than n2. If the value of n2 is
equal to or larger than the value of n1, the remainder of n2 / n1 (n2 devided by n1) is used
for a shift.
(3) This instruction specifies n1 ranged from 1 to 64.
(4) Bits starting from the highest bit to n2th bit are filled with 0s. If the value of n2 is larger than
the value of n1, the remainder of n2 / n1 will be 0.
(5) If the value specified by n1 or n2 is 0, the instruction will be not processed.
