When enabled, the BSER instruction searches the value 1 and saves the position number of the lowest bit to the D and the highest bit to the D+1.
D : The lowest bit position(4) is stored in D.
D+1 : The highest bit position(15) is stored in D+1.
If there is no value 1 in the source, D and D+1 will have 0 value.
If There is only 1 bit which has value 1, D and D+1 will have the same value.
Example)
If M01 is ON, the BSER instruction searches value 1 in the source (H1D1C). The lowest bit position 3 is stored in D100 and the highest bit position 13 is stored in D101.
