Notes on operand usage: none
 S1: Minuend. S2: Subtrahend. D: Difference.
 Subtracts S2 from S1 using the BIN method and stores result in D.
 The highest bit of any data defines the sign bit = 0 indicates (positive) bit = 1
indicates (negative); enables the use of algebraic subtraction operations.
 Flag changes connected with subtraction.
16-bit commend:
1. When calculation results are 0, the zero flag M1020 is ON.
2. When calculation results are less than -32,768, the borrow flag M1021 is ON.
3. When calculation results are greater than 32,767, the carry flag M1022 is ON.
32-bit commend:
1. When calculation results are 0, the zero flag M1020 is ON.
2. When calculation results are less than -2,147,483,648, the borrow flag M1021 is
ON.
3. When calculation results are greater than 2,147,483,6477, the carry flag M1022
is ON.
 16-bit BIN subtraction: When X0 = ON, subtracts the content of D10 from the
content of D0, and stores the difference in D20.
